Question

Find the circumference of a pizza if the diameter is 10 inches.

0.314 in.
3.14 in.
3.04 in.
31.4 in.

Answer 1

The circumference of a circle is:

C=πd, since we are told that d=10in

C=10π in

C≈31.4 in (to nearest tenth of an inch)

Answer 2

Answer: 31.4 in.

Explanation:

We know that the circumference of the circle is given by :-

`C=\pi d`, where d is the diameter of the circle.

Given : The diameter of the pizza = 10 inches

Then the circumference of the pizza will be :-

`C=\pi (10)`

We put the value of
`\pi =3.14`, we get

`C=3.14 (10)=31.4`

Hence, the circumference of a pizza is 31.4 in.
