If the ratio of circles to triangles you will only need to write ratios in one form of your choice

1 answer:

4 0

Answer:

Ratio of area of circles: = πr2 :πc2 = πr2 :π r2 4 = 4 :1. 1. The small equilateral triangle is rotated through 60° about O, the center of the circle. The arm of the rotation is the radius of the circle

Which equation represents the area of one base of a cylinder if the radius is doubled?

Svetllana [295]

Answer:

$B_2=4\pi r^2$

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

$B=\pi r^{2}$

where

r is the radius of the circular base

If the radius is doubled

then

$r=2r$

The new base area is

$B_2=\pi (2r)^{2}\\B_2=4\pi r^2$

$B_2=4B$

therefore

The new area of the base is 4 times the area of the original base
