Question

The solid described is similar to a larger solid with the given scale factor. Find the surface area and volume of the larger solid A right cylinder with a surface area of 48pi square centimeters and a volume of 45pi cubic centimeter; Scale factor 2:3

Answer 1

find the radius and height of the cylinder using the surface area and volume provided. since the scale is 2:3, you have to multiply the radius and height by 3/2 and to get the radius and height of the bigger cylinder. Use those values to calculate volume and S.A of the bigger cylinder.

Answer 2

huh?

Answer 3

what didn't you understand in the explanation I gave?

Answer 4

none of it.. sorry ive been doing math all day

Answer 5

surface area of the given cylinder is 48pi.
so 48 pi = 2pi * radius^2+ 2pi radius*height
volume is 45pi
so 45 = pi*radius^2*height
solve the two equations to get radius and height
new radius = 3/2 * radius
new height = 3/2 * height
use the new values to find the volume and surface area of the new bigger cylinder.

Answer 6

sorry it is 45pi = pi*radius^2*height
