Question

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___mi2.
The approximated value for the area is___.

Answer 1

1=9 2=28.3sm

Explanation:

1❤️=1

GOOD LUCK

Answer 2

9pi; 28.26

Explanation:

Area = pi(r^2), but we are using 3.14 instead of pi, so the area = 3.14 (r^2)

Plug in r:

Area = 3.14(9)

Area (approx)= 28.26

The actual area is 9pi
