Question

5. Aly ordered a pie that had a diameter of 8 in. What is the approximate area of the pie? (Use 3.14 for t)

Answer 1

50.24 square inches. If the diameter is 8in, then the radius must be half the diameter, or 4. You can just plug 4 into the formula for the area of a circle [A=pi*radius^2]. When you multiply 3.14 by 4^2, you get 50.24 square inches.
