Question

On May 14, 1898, a severe hailstorm hit Kansas City. The largest hailstones were 9.5 inches in circumference. Find the radius of one of the largest hailstones. The formula for the circumference of a circle is c =2nr.

Answer 1

C = $\pi$r
9.5 = 2$\pi$r
$\pi$r = 4.75
r = 1.511971959 
The number above should be rounded to the nearest 2 decimal places, so the answer is 1.51.
