Question

Find the area of a circle with a circumference of 6.28 units

Answer 1

area of the circle = 3.14 square units

Explanation:

Circumference of the circle formula is
`2\pir`

where r is the radius of the circle

given circumference = 6.28

`2\pir` = 6.28

Value of pi is 3.14

2*3.14 * r= 6.28

6.28 r = 6.28

divide by 6.28 on both sides

r = 1

radius = 1

Area of the circle =
`\pi r^2`

= 3.14 *1*1 = 3.14
