Question

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

A.
50 square feet

B.
100 square feet

C.
201 square feet

D.
803 square feet

Answer 1

`A = \pi r^2`

radius = half the diameter ------> 16/2 = 8


`A = \pi (8^2) = 64 \pi`

pi = 3.14

64*3.14 = 201

Answer 2

Well I believe that the equation for the area of a circle is
`\pi r^(2)`. Pi*Radius^2
The radius of the garden is 8ft because it's half of the diameter. 8^2 is 64. Multiply that by 3.14 and you will get approximately 201 square feet so the answer is:

C) 201 square feet
