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.
