Estimate the area of the top of a round pizza that has a diameter of 16 inches. round to the nearest tenth.

Given:
pizza with a diameter of 16 inches.

Find the Area of the top of a round pizza.

The top of a round pizza is still a circle. The formula of finding the area of a circle is multiplying pi to the radius of the circle, which is raised to the 2nd power.

Area of a circle = π r²

π is equivalent to 3.14 ; radius is 1/2 of the diameter.

radius = diameter/2 = 16 inches / 2 = 8 inches

Area of a circle = 3.14 * (8in)²
                        = 3.14 * 64 in²
Area of a circle = 200.96 in²

200.96 in² rounded to the nearest tenth is 201.0 in²
