Question

The diameter of a circular garden is 16 feet. What is the approximate area of the garden?

Answer 1

A diameter is twice as much as a radius. So in this case you divide the diameter by 2 which then becomes 8. Then the formula of a circle is 2(pi)(R) = approximately 50.27 ft

Answer 2

Since the garden is circular, you will have to find the area of a circle. The formula is:

`\pi * r^(2)`

The diameter is 16 feet. Radius is ½ of the diameter. To find the radius, divide the diameter by 2.

`d = 16 \\ 16 / 2 = 8 \\ \\ r = 8`

Square the radius

`r = 8 \\ 8^(2) = 8 * 8 = 64`

Multiply by π(3.14)

`64 * 3.14 = 200.96`

The area of the garden is 200.96 feet
