The circumference of a pizza is about 38 inches. What is the diameter of the pizza? Round to the nearest tenth if necessary

anygoal [31]

Answer:

The diameter of the pizza is 12 inches

Step-by-step explanation:

Given:

Circumference of a pizza = 38 inches

To Find:

The Diameter of the pizza =?

Solution:

Circumference:

The distance around the edge of a circle (or any curvy shape). It is a type of perimeter.

We know that the shape of the pizza is circle.

So the given circumference is circumference of a circle.

Now,

Circumference of the circle(pizza)= $2\pi r$

where r is the radius of the circle

circumference of the pizza =38

Thus

$2\pi r= 38$

$\pi r=\frac{38}{2}$

$\pi r=19$

$r=\frac{19}{3.14}$

r=6.050 inches

Now,

Diameter = $2\times r$

Diameter = $2\times 6.05$

Diameter=12.1 inches

Rounding to the nearest tenth

Diameter=12 inches
