A right cylinder has the radius of 5 centimeters and height of 22 centimeters.

Round to the nearest tenth.

I need to find -

Find Lateral Area

and

Find Surface area

recall that lateral area (area on the sides, not the top or the bottom) of a cylinder is given by,

LA = 2πrh

where

r = radius

h = height

π = "pi" equal to 3.14 (constant)

substituting,

LA = 2*(3.14)*5*22

LA = 690.8 cm^2

recall that the surface area of cylinder is the sum of the lateral area and area of the base, given by

SA = 2πrh + 2πr^2

where

r = radius

h = height

π = "pi" equal to 3.14 (constant)

substituting,

SA = 2*(3.14)*5*22 + 2*(3.14)*5^2

SA = 847.8 cm^2

hope this helps~ :)
