Question

how to find the area of each circle. use a calculator value of pi. round the answer to the nearest tenth

Answer 1

Answer:

A = 201.0 mi^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know that r = 8

A = (3.14) *8^2

A = 3.14 * 64

A = 200.96 mi ^2

Rounding to the nearest tenth

A = 201.0 mi^2

Answer 2

Answer:

201.1 mi

Step-by-step explanation:

1. Use the formula for area of a circle which is A=pi r^2

2. Plug in 8 for r (representing the radius):

8^2= 64 x pi = 201.1
