Question

What is the area of a circle with a radius of 7 cm? (Use 3.14 for and round to the nearest tenth.)

Answer 1

Answer:

A =153.9 cm^2

Step-by-step explanation:

We know the area of a circle is given by

A = pi r^2

We are given the radius and pi

A = 3.14 (7)^2

A =153.86 cm^2

Rounding to the nearest tenth

A =A =153.9 cm^2

Answer 2

The area is pi times the radius squared, which would be 49 pi, or 49*3,14, which is 153,86. Rounding, it would be 153,9.
