The height of a cylinder is equal to its radius. If the volume is 0.216 \(\pi m^3\) Calculate the radius.

Wrong.

Volume of cylinder =pie*r^2*h

h=r

0.216pie=pie*r^2*r

0.216pie=pie*r^3

R^3=0.216

R=cube root of 0.216

r=0.6

my school plss review dis question
it ain't 0.4
the answer is 0.60
they said the height equals radius
if height is taken as h den since it equals radius it will be h=r,changing the formula to V=πr³
0.216π=π×r³
d.b.s by π leaving 0.216=r³,taking cube root of both side you'll get 0.6 and dats the answer....pls correct the answer
thanks

how is h = 1 abeg?
didn't you say h = r in the question?
