Question

What is the area and circumference of a 12-inch pizza (diameter)?

Answer 1

A=36
`\pi`
`inches^(2)`

C=12
`\pi` inches

Explanation:

Answer 2

37.68

Explanation:

To find the circumference of a circle, use the formula π x d. The d meaning the diameter.

You can also use 3.14 for π.

So the equation is 3.14 x 12 = C

3.14 x 12 = 37.68

So C (circumference) equals 37.68 sq. inches!

Now for area...

The formula to find the area of a circle is πr².

r means the radius.

To find the radius, just divide the diameter by 2.

So if the diameter is 12, the radius is 6.

Using 3.14 for π, the equation would be 3.14 x 6² = A (area)

6² = 36

36 x 3.14 = 113.04

So the area of the circle is about 113.04 sq. inches!
