Question

A basketball team wants to paint half of a free-throw circle grey. If the radius of the free-throw circle is 5.4 feet, what is the area that will be painted grey? Use 3.14 for , and round to the nearest square foot.

Answer 1

Answer:

The area which would be painted grey will be "47.7812 ft²".

Step-by-step explanation:

The given values are:

Radius of circle, r = 5.4 feet

Value of pi, π = 3.14

As we know,

Area of Semicircle = $\frac{\pi r^2}{2}$

On putting the values in the above formula, we get

                               = $\frac{3.14\times (5.4)^{2}}{2}$

                               = $\frac{3.14\times 29.26}{2}$

                               = $\frac{91.5624}{2}$

                               = $45.7812 \ ft^2$
