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:$454.019\ ft^2$

Step-by-step explanation:

Given

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

So, its radius is $r=\dfrac{34}{2}=17\ ft$

Area of semi-circle is $\dfrac{\pi r^2}{2}$

$\therefore \text{Area of semi-circle is }=\dfrac{\pi r^2}{2}\\\\\Rightarrow A=\dfrac{\pi \cdot 17^2}{2}\\\\\Rightarrow A=454.019\ ft^2$

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