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

choices
6 in.

12.1 in.

12.7 in.

24.2 in.

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)=

where r is the radius of the circle

circumference of the pizza =38

Thus

r=6.050 inches

Now,

Diameter =

Diameter =

Diameter=12.1 inches

Rounding to the nearest tenth

Diameter=12 inches

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
