Question

If a radius of a circle is 12 feet, what is the area and perimeter of the circle?

Answer 1

Area: 452.4

Perimeter: 75.4 ft

Explanation:

Formula for area:
`\pi r^(2)`

Formula for perimeter:
`\pi d` or
`2\pi r`

Answer 2

area of a circle=πr²
area of this cirlce=π*(12 ft)²=144π ft²≈452.39 ft².

answer 1= the area of this circle is 452.39 ft².

Perimeter of a circle=2πr.
Perimeter of this cirlce=2π(12 ft)=24π ft≈75.4 ft

answer 2= the perimeter of this cirlce is 75.4 ft.
