use the formula for the area of a circle. Pi•R squared. plug in the information and solve.
example:
radius:2
(3.14)(2)squared *2•2=4*
(3.14)(4)=12.56
if needed, round.
12.56 estimated is 12.6 *if there are no units, put units*
12.6 units squared
*if they give you units then use the units they give you.*
that's it peeps.

How do you get the area of a cylinder base in fifth grade math.?
The base of a cylinder is a circle. So we can use the area formula for a circle. Area = πr2 where r is the radius of the circle, and pi is the ratio of the circumference of the circle to its diameter.
What is the area of a circle whose diameter is 75mm?
A=πr2Plug in the radius. Do the math.
