Area = 28.27cm^2Area=28.27cm2

Explanation:

The area of a circle can be obtained by using the equation below:

where the mathematical constant, piπ, has a value of approximately 3.14 and rr represents the radius of the circle.

All we have to do is square the given radius and multiply that value by piπ to figure out the area:

Area = (3cm)^2 xx piArea=(3cm)2×π
Area = 28.27cm^2Area=28.27cm2
