Question

Given a circle with a radius of 0.85 meters, find the area of 1/3 of the circle. Use 3.14 for pi and round to the nearest hundredth.

Answer 1

r=0.85
pi=3.14

`(1)/(3) area \: of \: a \: circle = (1)/(3)( \pi * {r}^(2) )`

`(1)/(3) * 3.14 * ( (85)/(100) ) ^(2) = 0.76`

Answer 2

.76 meters

Explanation:

The area of a circle is pi*r^2

3.14*.85^2 = 2.26865

Dividing this into thirds gives us approximately .75621666666

Round to the nearest hundredth.

.76

Label the answer.

.76 meters
