Answer 1

The formula for the area of a circle is A = πr², where r is the radius.
Plugging in the given radius of 7 inches:

A = π * 7²
A = 49π

To round to the nearest tenth, we can approximate the value of π to 3.14:

A = 49 * 3.14
A ≈ 153.86

Therefore, the area of the circle with a radius of 7 inches is approximately 153.9 square inches.
