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.

Step-by-step 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.
