Question

Mr. Martinez is having the half court circle in the gym repainted. They are

going to outline the circle in red. The inside of the circle will be painted
black. The circle has a diameter of 26 units.
3. To determine how much black paint to buy, he asks the custodian to
determine the area of the circle. What is the area of the circle to the
nearest hundredth of a square unit?
Area = TER?

Answer 1

The area of the circle is 531.14 square unis

Explanation:

Area of a circle =
`\pi`
`r^(2)`

where r is the radius of the circle

Given that the diameter of the circle = 26 units, the radius can be determined by;

r =
`(diameter)/(2)`

=
`(26)/(2)`

r = 13 units

So that,

Area of the circle =
`(22)/(7)` x
`(13)^(2)`

=
`(22)/(7)` x 169

= 531.1429

The area of the circle is 531.14 square unis.
