Question

Find the area of a circle with a diameter of 16

Answer 1

Answer: A = 64
`\pi` = 201.061

Explanation:

The equation to find the area of a circle, is:

`A=(1)/(4) \pi d^2`

-Next, you place the diameter onto the equation:

`A=(1)/(4) \pi 16^2`

-Then, you solve:

`A=(1)/(4) \pi 16^2`

`A = (1)/(4)`
`\pi` ×
`256`

`A=(256)/(4) \pi`

`A=64\pi = 201.061`

Answer 2

201.06

Explanation:

Area of circle:
`A=\pi r^2`

r = 1/2d = 1/2(16) = 8

`\pi *8^2 = 201.06`
