Answer:
r = 0.8923
Step-by-step 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.
