Question

The three point line on a basketball court forms a semi circle. For middle school, it has a diameter of 34 feet. What is the area of the semi circle?

Answer 1

Answer:
`454.019\ ft^2`

Explanation:

Given

Diameter of semi-circle is
`d=34\ ft`

So, its radius is
`r=(34)/(2)=17\ ft`

Area of semi-circle is
`(\pi r^2)/(2)`

`\therefore \text{Area of semi-circle is }=(\pi r^2)/(2)\\\\\Rightarrow A=(\pi \cdot 17^2)/(2)\\\\\Rightarrow A=454.019\ ft^2`

Thus, the area of semi-circle is
`454.019\ ft^2`
