Question

Determine the radius of the circle.
The radius rounded to the the nearest whole number_____.

Answer 1

39.7994974843 or 40

Explanation:

We must use the Pythagorean Theorem to get the radius. First, we must do 53 squared minus 35 squared to get b squared. This equals 2,809 minus 1,225 equals b squared. This equals 1,584 equals b squared. Now we must find the square root of 1584 and b squared. The radius is 39.7994974843 but we can round it to 40.
