A circular pie with a diameter of 9.8 inches is cut into 7 equal slices. What is the approximate area of one slice?

A = pi * r^2

A = 3.14 * 4.9^2
A = 3.14 * 24.01 sq. inches

24.01 / 7 = ?

3.43 To find the approximate area of one slice of a circular pie, you need to first find the area of the entire pie, and then divide it by the number of slices.

The area of a circle can be calculated using the formula: A = π * r^2, where A represents the area and r represents the radius of the circle.

In this case, we are given the diameter of the pie, which is 9.8 inches. The radius (r) of the circle is half of the diameter, so r = 9.8 / 2 = 4.9 inches.

Now we can calculate the area of the entire pie using the formula. Using an approximation for π as 3.14, we have A = 3.14 * (4.9)^2 = 75.207 square inches.

Finally, to find the approximate area of one slice, we divide the area of the entire pie by the number of slices. So, the approximate area of one slice is 75.207 / 7 = 10.887 square inches.
