Answer:
±sqrt(4a/ π b)= c
Step-by-step explanation:
a= 1/4 π b c^2
Multiply each side by 4 to get rid of the fractions
4a= 4*1/4 π b c^2
4a= π b c^2
Divide each side by pi b to isolate c^2
4a/ π b= π b c^2 / π b
4a/ π b= c^2
Take square root of each side
sqrt(4a/ π b)= sqrt( c^2)
± sqrt(4a/ π b)= c
