Question

You can buy a circular pizza with a circumference of 40 inches or a 10in by 10in square pizza( a perimeter of 40 inches) which pizza would give you more pizza?

Help me please!!

Answer 1

Answer: Circular pizza

Step-by-step explanation:

C = circumference of a circle of radius r

C = 2*pi*r

40 = 2*3.14*r

40 = 6.28r

r = 40/6.28

r = 6.37

A = area of the circle of radius r

A = pi*r^2

A = 3.14*(6.37)^2

A = 127.41

A = 127

The area of the circular pizza is roughly 127 square inches.

The other pizza has an area of 10*10 = 100 square inches. The circular pizza is slightly larger in area, which means you should go for the circular pizza.
