The centre circle has a diameter of 3 cm and the difference in the radii of each larger circle is 4 cm. What is the circumference of the yellow circle? Use π=3.14
Circumference = 2×π× radius
Circumference = 2 × 3.14 × 3
Circumference = 18.84
Solution for the radius of a circle of radius 3 . I'm sorry if I made a mistake, I am not sure of the solution.
But is there a fee for the question?
These two laws can help you in the question:
Circumference = π× diameter of the circle. Circumference = 2×π× radius
The circumference of the yellow circle should be considered as the 18.84.
Calculation of the circumference of the yellow circle:Since
The centre circle has a diameter of 3 cm and the difference in the radii of each larger circle is 4 cm
So here the circumference be like
= 2×π× radius
= 2 × 3.14 × 3
= 18.84
hence, The circumference of the yellow circle should be considered as the 18.84.

Answer:
-13x+5
Step-by-step explanation:
Distributive Property
-4 (2.5x) + (-4)(-1.25) - 3x
Multiply 2.5 by -4
- 10x - 4 * 1.25 - 3x
Multiply -4 by 1.25
- 10x + 5 -3x
Subtract 3x from -10x

Find the area. Round any decimals to the nearest tenth
Answer:
1.4
Step-by-step explanation:
Since we're finding the area, we need to multiply 1.2 times 1.2, which would give us 1.44, and since it says to round to the nearest tenth, we need to round it. If the number is 4 or under, we round down, if it's 5 and up we round up. In this case, we round down- so we end up with 1.4.
Answer:
A = L x 4
1.2cm x 4 = 4.8 cm^3

In Circle P, EP = 2, PG = 12, and FP = 4.
What is the measure of PH?
A) 10
B) 16
C) 6
D) 8
Answer:
6
Step-by-step explanation:
FP * PH = GP * EP
If EP = 2, PG = 12, and FP = 4.
Then 4 * PH = 12 * 2
4 * PH = 12 * 2
step 1 simplify
4 * ph = 4PH
12 * 2 = 24
we now have 4PH = 24
step 2 divide each side by 4
4PH / 4 = PH
24 / 4 = 6
we're left with PH = 6

What minus 9 equals 11
Answer:
20
Step-by-step explanation:
20 - 9 = 11
I hope this helps
Answer:
20
Step-by-step explanation:
Call the number you're trying to find n.
"What" becomes n.
n - 9 = 11
To "undo" the subtraction and reveal the value of n , ADD 9 to both sides of the equation. (Addition is the inverse operation of subtraction.)
n = 11 + 9 = 20

What is the portion if the base is 450 and the rate is 19%
Answer:
portion = 85.50
Step-by-step explanation:
[tex]Rate = (\frac{Portion}{Base})*100%[/tex]
Rate = 19%, Base = 450
[tex]19 = \frac{portion}{450} \times 100\\\\19 \times 450 = portion \times 100\\\\\frac{8550}{100} = portion \\\\portion = 85.50[/tex]

A line with a slope of 1 passes through the point (6,2). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = x - 4
Step-by-step explanation:
Given:
Passes through (6, 2)
m = 1
Slope-intercept:
y - y1 = m(x - x1)
y - 2 = 1(x - 6)
y - 2 = x - 6
