The height of a cylinder is equal to its radius. If the volume is 0.216 \(\pi m^3\) Calculate the radius.
-
0.46m
- 0.60m
- 0.87m
- 1.80m
The correct answer is: A
Explanation
volume of cylinder = \(\pi r^2\)h0.216\(\pi m^3 = \pi \times r^2 \times 1m\)
assumed that h = 1m
0.216 = r2
r2 = 0.216
r = \(\sqrt{0.216}\)
= 0.46
