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

Answer: $\frac{29}{6}$

Step-by-step explanation:

To make an improper fraction, make the whole number into a fraction with the denominator 6. We do this because we want the fraction and the whole number to have the same denominator, so we can later add them together.

To do this, multiply 4 by 6:

$\frac{4 }{6}$ * $\frac{6}{1}$ = $\frac{24}{6}$
