Can you help me with this question?

  (49π)/8 = 6.125π square inches

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr² . . . . . where r is the radius

A "14-inch" pizza has a diameter of 14 inches, so a radius of 7 inches. Then the area of the whole pizza is ...

  A = π(7 in)² = 49π in²

The area of one of 8 equal slices will be 1/8 of that, or ...

  slice area = (49π in²)/8 = 6.125π in²

The area of one slice of pizza is (49/8)π = 6.125π square inches.
