Tony was looking at a pizza menu and ordered a circular pizza with a 14 inch diameter. What is the approximate area of the pizza?
49 square inches
88 square inches
154 square inches
616 square inches
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter of the pizza is 14 inches, the radius would be half of that, which is 7 inches.
Plugging the radius into the formula, we get:
A = π(7)^2
A = π(49)
A ≈ 154 square inches
Therefore, the approximate area of the pizza is 154 square inches.
