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: 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.
