Answer:

r = 0.8923

Explanation:

pi = 3.14

2.50 = 3.14 * r^2 Divide by 3.14

2.50/3.14 = 3.14*r^2 / 3.14

.7962 = r^2 Switch

r^2 = 0.7962 Take the square root of both sides.

sqrt(r^2) = sqrt(0.7962)

r = 0.8923 Answer


I don't know where you are getting stuck. Maybe it's finding the square root. You can do that on almost any calculate by

  • clearing the calculator and then
  • pressing the √ and put in 0.7962
  • =

Perhaps it is the value of pi. The usual approximation is 3.14. Take that as your value.
