A circular pie has a radius of 7 inches. A square pie has a side length of 12 inches. Which pie is larger?

Answers

Answer:

The circular pie

Step-by-step explanation:

The formula for the area of a circle is A=πr^2

Plugging in the radius gives us

A= π 7^2 then,

A= π 49

A= 153.94

Now the formula for the area of a square is A= a^2

Plugging the side length gives us

A = 12^2

A = 144

So 153.94 > 144
