cone A and cone B are similar. The radius of cone a is 5.4 feet and the radius of cone b is 16.2 feet. if the surface area of cone a is 43 square feet, find the surface of cone b

Answers

Answer 1
129 is the answerrrrrrrrr
Answer 2

The surface area of cone B is 387 square feet.

What is a cone?

It is a shape of a christmas tree where there is a base of radius r and a top point called the apex.

We have,

Since the cones are similar, their corresponding dimensions are proportional.

In particular, the ratio of their radii is equal to the ratio of their surface areas.

Now,

Let S be the surface area of cone B, then we have:

ratio of radii = 16.2/5.4 = 3

ratio of surface areas = S/43

Since the ratio of surface areas is equal to the ratio of radii squared,

We have:

3² = S/43

9 = S/43

S = 9 x 43

S = 387

Therefore,

The surface area of cone B is 387 square feet.

A rectangular prism has a base with a length of 45 meters and a width of 11 meters. The height of the prism measures twice its width. What is true about the rectangular prism?
The height of the prism measures( )meters, so its volume is ( )cubic meters.

Answers

Answer:

The height of the prism measures 22 meters

The volume of the prism measures 10,890 cubic meters.

Step-by-step explanation:

The height is twice the width of the prism.

The prism's width is 11 meters.

2 x 11 = 22

The volume of a rectangular prism is calculated as:

V = l x w x h

So, the volume is:

V = 45 x 11 x 22

The volume is 10,890 cubic meters.

Hope this helps!

Answer:

Height = 22 Volume = 10890

Step-by-step explanation:

The width is 11 so multiply by 2 to get 22.

Then just do 45 x 11 x 22 which is 10890.

Out of the 75 surveyed, the total number of those are:

= 24

That would give a percentage of:

= 24 / 75

= 32%

This means that the best estimate for those who will visit more than 3 times is 32%.

Out of the total number of 516, that is:

= 32% * 516
