Question

Find the area of a circle with a diameter of 14 meters. Round your answer to the nearest hundredth of a square meter.

Answer 1

To find the area of the circle:

 ⇒ need to know the formula: $\pi r^{2}$

• r: radius or half of diameter's length ⇒ 7 meters

Let's calculate:

 $Area = \pi (7)^2=49\pi =153.9380m^3$

The problem asks us to round to the nearest hundreth:

$Area = 153.94m^3$

Answer: $153.94m^3$

Hope that helps!
