The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π. show you work.
Answer:
14 meters²
Step-by-step explanation:
Since the formula to find the diameter is [tex]d=2r[/tex], we need to first find the radius, which can be [tex]r=\frac{\sqrt{A\pi}}{\pi}[/tex] if we take the formula for the area of a circle and isolate the radius. After simplifying [tex]r=\frac{\sqrt{153.86\pi}}{\pi}[/tex] to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!

Answer:
1) a. 15ft
b. 6ft
c. 30ft
2) a. 16m
b. 12m
c. 192m
answer for the 1st question:
1) length is 15 ft
2) width is 6ft
3) the area is 90 ft²
step-by-step explanation:
ok so we know that the plan is 2 in/6 ft
step 1-
we need to find the length of the terrace, and we know that the length of the terrace in the plan is 5 in
so by proportion- we'll need to find the length of the 'actual' terrace
2 in/ 6 ft= 5 in/ x ft
x=6*5/2
x=15 ft (we now have the length)
step 2-
now that we know the length, we need to find the width
the length of the terrace in the plan is 2 in
and by proportion- we'll find the 'actual' width of the terrace
2 in/6 ft=2 in/ x ft
x=6*2/2
x=6 ft
and now we'll find the area of the terrace (step 3)-
the formula for the area of a rectangle is a=lw or area=length*width
now we just fill the variables in with what we know-
so we know that 15 ft is the length and that 6 ft is the width-
15*6=90 ft²

The diameter of a circular garden pool is six feet. What is the area of the pool?
Answer:
113.04
Step-by-step explanation:
Given: circle k(O), diameter US, measure of arc RU=50, measure of arc UT=30
Find: measure of angle RUS and measure of angle UST
Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.
The measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.
What is Thales theorem?The angle ABC is a right angle if A, B, and C are different points on a circle where the line AC is a diameter, according to Thales' theorem.
We know that when an angle is made by the diameter of a circle at its circumference, then the measure of that angle is 90°.
In ΔUST,
The angle made by the diameter is ∠UST, therefore, the measure of this angle will be 90°. Since the measure of the arcRU=50°, therefore,
arcRU = ∠ROU = 50°, Also,
[tex]\angle RSU=\dfrac{\angle ROU}2 =\dfrac{50^o}2 = 25^o[/tex]
Now, the sum of the angles of a triangle is 180°.
∠R+∠U+∠S=180°
90°+∠RUS+25°=180°
∠RUS = 65°
In ΔRUS,
The angle made by the diameter is ∠URS, therefore, the measure of this angle will be 90°. Since the measure of the arcUT=30°, therefore,
arcUT = ∠UOT = 30°, Also,
[tex]\angle UST=\dfrac{\angle UOT}2 =\dfrac{30^o}2 = 15^o[/tex]
Thus, the measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.

Answer:
The first one is proportional and the second one is not. Because for the first one you can see that if you divide the number of pens by the cost you'll get the same answer for every single one. But for the second one if you divide the number of minutes by words typed you get a different answer for each one. You can also see if it's proportional or not if you draw it on the graph and it's a straight line. If it is the relationship is proportional if it isn't it's not proportional. Hope that makes sense :)
Determine whether the relationship between the two quantities shown in the table or graph is linear. If so, find the constant rate of change. If not, explain your reasoning. 1. SOLUTION: Analyze the table. The rate of change from 5 hours to 8 hours is or 3 cents per hour. This is the same as therate of change from 8 hours to 12 hours, or 3 cents per hour, and from 12 hours to 24 hours, or 3 cents per hour. So, the rate of change is a constant 3¢ per hour. ANSWER: Yes; the rate of change between cost and time for each hour is a constant 3¢ per hour. e i dont know if this is the answer to ur question but here u go

You and your friends went to UNO's for dinner (way back in 2019). Together the total bill for your meals was $40. You have a 15%-off coupon for the meal! Then, after the discount, a 7% sales tax is applied. What is the final price, after the discount and the tax, that you are your friends have to pay for the meal?
Answer:
$36.38
Step by step explanation:
First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.
This gives us $0.40.
To then find out fifteen percent of $40, you then times $0.40 by 15.
This gives us 6 dollars.
Now, to work out the discount, we take 6 from 40.
$40 - $6 = $34
Now we have to work out the tax.
Again, we have to work out what 1% of $34 is.
This gives us $0.34
Then times that by 7 to find 7%
0.34 x 7 = $2.38
Since this is tax we have to add instead of subtracting.
$34 + $2.38 = $36.38 as the final bill.
