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
