How many square inches of crust would it take to cover the bottom of a pie dish with a 15 inch diameter
What is the area of the crust?
A = pi * r^2
A = 3.14 * 7.5 * 7.5
To find the number of square inches of crust needed to cover the bottom of a pie dish with a 15-inch diameter, you can use the formula for the area of a circle.
The formula to calculate the area of a circle is:
Area = π * (radius)^2
In this case, the diameter of the pie dish is given as 15 inches. The radius is half the diameter, so we can calculate it by dividing the diameter by 2:
Radius = 15 inches / 2 = 7.5 inches
Now, we can substitute the radius value into the formula to find the area:
Area = π * (7.5 inches)^2
The value of π (pi) is approximately 3.14159. Using this value, we can calculate the area:
Area = 3.14159 * (7.5 inches)^2
Calculating further:
Area = 3.14159 * (7.5 inches * 7.5 inches)
Area = 3.14159 * 56.25 square inches
Finally, let's calculate the area:
Area ≈ 176.715 square inches
Therefore, it would take approximately 176.715 square inches of crust to cover the bottom of a pie dish with a 15-inch diameter.
