Question 2
What is the LATERAL SURFACE AREA of this cylinder?

The lateral surface area is the area of the side thing, not the 2 circles.

If we imagine to stretch the side out, we can get a rectangle with base the circumference to the base circle, and height of 9 inches.

Therefore this area is pi*8*9=72π

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
