A semicircle has an area of 76.97 squared km. Find it’s radius
shtirl [24]

Answer:

7 km

Step-by-step explanation:

Substitute:

The equation for area of a semi-circle is \frac{r^{2}\pi }{2}

A =  \frac{r^{2}\pi }{2}

76.97 =  \frac{r^{2}\pi }{2}

Multiply by 2 on both sides:

2(76.97) = ( \frac{r^{2}\pi }{2})2

153.94 = r^{2} \pi

Divide by pi on both sides:

153.94 = r^{2} \pi

/pi           /pi

49.03 ≈ r^{2}

Find the square root:

\sqrt{49.03} =\sqrt{r^{2} }

7 = r
