The most popular pizza's pizza. What is the area of a pizza with a diameter of 10 inches? Round your answer to the nearest hundredth.

Question

I need this answer for my question for my homework.

Answer 1

Area is given by

A = πr²

 

The radius is half the diameter or r = d/2

Since the diameter is 10 inches, the radius is 5 inches

 

A = π(5²) = 25π

 

If you use the pi key on the calculator and multiply this

you get A = 78.54 sq in.

 

 

Answer 2

Area of a circle = Pi*R^2 = Pi*D^2/4. Here R is radius and D is diameter of the circle.

 

D is given. So one can find the area easily.
