Question

The solid is similar to a larger solid with the given scale factor, find the surface area and volume of the larger solid. 1) Cylinder: scale factor 1:2, SA=208pi in^2, V=320pi in^3 2)rectangle: scale factor 1:3, SA= 398in^2, V= 495in^3 3) cone: scale factor 3:4, SA=96pi cm^2, V=96pi cm^3

Answer 1

i dont understand how to solve these

Answer 2

Its dealing with ratios. So you first have to know what the ratio are. It is given here in these problems.

Answer 3

in the first problem the ratio is 1:2.

Answer 4

what does that mean? It means that the size of the second object is going to be twice of that of the first.

Answer 5

so the new ratio would be 4:8

Answer 6

so the surface area is given as 208Pi^2

Answer 7

that is of the one you are comparing it with

Answer 8

ok

Answer 9

i still dont know what to do
