Please help<br>Find the unknown radius of the circle. A measures 628 sq cm find r

stira [4]

Answer:

14.14 cm

Step-by-step explanation:

The formula for the area of a circle is : $\pi *radius^2$

In order to find the radius you would first have to divide the area of 628 by pi, this gives you 200. This is because by dividing the area by pi it will leave us with the radius squared.

The next step is to find the square root of 200, this gives us 14.14. This is because by finding the square root it will leave us with the radius. The square root is another number that when multiplied by itself equals the number.

1) Divide 628 by pi.

$628/\pi =200$

2) Find the square root of 200.

$\sqrt{200}=14.14$
