Question

The diameter of a circle is 16 inches. What is the circle’s area?

Use 3.14 for pi

Answer 1

200.96

Explanation:

We know that the area of a circle is
`\pi r^2`

But we are given the diameter. Diameter is two times radius, so:
`\frac{\text{diameter}}{2}=\text{radius} = (16)/(2)=8\\`

We now know that 8 is our radius. Then, we will use the formula to solve.

`\pi r^2=\pi8^2=64\pi \text{ or } 200.96`|
