How about 5 times 289 = 1445 as one example
The answer is 17 because 17*17=289 I start very close to it then do multiplication. 15^2=225 16^2 =256 17^2=289
1 x 289 = 289
17 squared = 289
Recall the equation A = pi * r^2. You've given the information that A = 289 pi. Now, simply solve the equation for r: A = pi * r^2 289 pi = pi * r^2 289 = r^2 sqrt(289) = r 17 = r
17 to the power of 2 = 172 = 17 x 17 = 289
289/x=96r1 x = 289/96r1
The idea is to take the square root of 289. You can do that on any calculator.Note: The calculator will give you a positive number. The NEGATIVE of the number which the calculator gives you is also a valid solution.
