Question

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

Answer 1

Answer:

Area: 452.4

Perimeter: 75.4 ft

Step-by-step 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.
