Question

The radius of a circle is 42 inches. What is the circle's area?
Use 3.14 for ​.

Answer 1

Answer:

A =5538.96 in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the radius is 42 and pi is approximated by 3.14

A = 3.14 * 42^2

A =5538.96 in^2

Answer 2

Answer:

5,538.96 in

Step-by-step explanation:

A=π r^2

Remember r^2 is r * r.

r^2 = 42*42= 1,764

A= 3.14 * 1,764 = 5,538.96in
