Question

If the base of a round wedding cake is 20 inches in diameter, the area of the base is

square inches.

Answer 1

`Area = 314\ in^2`

Explanation:

Given

`D = 20\ in` -- Diameter

Required

Determine the area

First, we calculate the radius (r)

`r = (1)/(2)D`

`r = (1)/(2)*20`

`r = 10`

The area is then calculated as:

`Area = \pi r^2`

`Area = 3.14 *10^2`

`Area = 3.14 *100`

`Area = 314\ in^2`
