Question

The area of the circle is 1384.74 units squared. What is the surcumfrence of the circle

Answer 1

131.88 units

Explanation:

Area of the circle = π
`r^(2)` = 1384.74 sq. units

`r^(2)` =
`(1384.74)/(3.14)` = 441 =
`21^(2)`

r = 21 units

Circumference of circle = 2πr = 2*3.14*21 = 131.88 units
