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

Answer:

.76 meters

Step-by-step 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

Answer 2

R=0.85
pi=3.14
$\frac{1}{3} area \: of \: a \: circle = \frac{1}{3}( \pi \times {r}^{2} )$
$\frac{1}{3} \times 3.14 \times ( \frac{85}{100} ) ^{2} = 0.76$
