Need help again thanks guys!!

A = 225 pi cm^2

Using 3.14 for pi

A =706.5 cm^2

Using the pi button for pi

A =706.8583471 cm^2

Step-by-step explanation:

The area of a circle is

A = pi r^2

A = pi (15)^2

A = 225 pi cm^2

Using 3.14 for pi

A =706.5 cm^2

Using the pi button for pi

A =706.8583471 cm^2

225π cm^2, 706.5 cm^2, 706.858... cm^2

Step-by-step explanation:

The area of a circle can be found using the following equation:

We know the radius is 15 cm, so we can substitute 15 cm in for r.

1. In terms of pi

To find the area in terms of pi, evaluate everything possible without multiplying by pi.

Evaluate the exponent.

15cm^2= 15 cm * 15 cm = 225 cm^2

This can be rewritten as:

2. Using 3.14 for pi

Substitute 3.14 in for pi.

Multiply

3. Using 3.14159265.... as pi

Multiply, using the pi button on a calculator
