1130.97 is the surface area of the cylinder

6 0

Assuming the cylinder is closed at both ends

S A = 2 pi r^2 + pir^2h
= 2 pi 6^2 + pi 6^2 24
= 226.2 + 2714.3
= 2940.5

If the cyilnder is open at both ends the surface area is 2714.3

Given:

$PQRS\sim TUVW$

In the given figure, PS=x, RS=35, UV=20, VW=25 and TW=15

To find:

The scale factor from PQRS to TUVW.

Solution:

We have,

$PQRS\sim TUVW$

We know that the corresponding sides of similar figures are proportional. The scale factor is the ratio of one side of image and corresponding side of preimage.

The scale factor is:

$k=\dfrac{VW}{RS}$
