Question

Calculate the circumference and area of this circle

Answer 1

Circumference = 10
`\pi` or 31.4

Area = 25
`\pi` or 78.5

Explanation:

Circumference formula is
`2\pi r`

Plug in the radius of 5 for the equation:

`2\pi 5` or
`10\pi`

Area formula is
`\pi r^(2)`

Plug in the radius of 5 for the equation:

`\pi 5^(2)` or
`25\pi`
