Question

what is the length of the radius of a circle whose area is equal to 7234.56m^2?

Answer 1

Answer:

Area of circle = 7234.56m^2

πr^2 = 7234.56

22/7×r^2 = 7234.56

r^2 = 7234.56 × 7/22

Multiply the numbers

r^2 = 50641.92/22

Convert decimal to fraction

r^2 = 1266048/25/22

Simplify the fraction

r^2 = 633024/275

Simplify the equation

The final solutions are

r = 24√12089/55m

and r = -24√12089/55m
