Use 3.14 for pie to estimate the area of the circle diameter is given round your answer to the nearest hundredth if necessary

The area of a circle can be found using the equation π r²

Since the diameter is 28.2 we need to divide by 2 to get the radius which would be 14.1

(3.14)×(14.1²) = (3.14)×(198.81) = 624.2634
when rounded to the hundredth the answer is 624.26
