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)=
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
