A circle has a radius of 3 miles. Use the work shown below to identify the area in terms of pi and the approximate area of the circle. Use 3.14 for π and round the answer to the nearest tenth.
A = πr2
A = π(3 mi)2
A = 3.14(9 mi)
The area in terms of pi is Pi mi2.
The approximated value for the area is .
