Question

If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)

Answer 1

113.04 units²

Explanation:

A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference or perimeter r = radius, d = diameter

Hope this helps

Answer 2

Area of the circle =
`113.04\;units^2`

Explanation:

Circumference =
`37.68\;units`

Circumference of the circle =
`2* \pi * r`

As,

`\pi =(22)/(7)=3.14`

`37.68=2* \pi * r\\\\37.68=2* 3.14 * r\\\\37.68=6.28* r\\\\r=(37.68)/(6.28) \\\\r=6\;units`

Area of a circle =
`\pi * r^2`

`=3.14* (6* 6)\\\\=3.14* 36\\\\=113.04\;units^2`
