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

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

Explanation:

The given values are:

Radius of circle, r = 5.4 feet

Value of pi, π = 3.14

As we know,

Area of Semicircle =
`(\pi r^2)/(2)`

On putting the values in the above formula, we get

=
`(3.14* (5.4)^(2))/(2)`

=
`(3.14* 29.26)/(2)`

=
`(91.5624)/(2)`

=
`45.7812 \ ft^2`
