Question on: JAMB Mathematics - 2002
A
198\(\pi cm^3\)
B
180\(\pi cm^3\)
C
162\(\pi cm^3\)
D
216\(\pi cm^3\)
Ask EduPadi AI for a detailed answer
Correct Option: A
V = \(\pi r^2 h + \frac{2}{3} \pi r^3\)
N.B h = r
V = \(\pi x (3)^2\) x 20 = \(\frac{2}{3} \times \pi \times (3)^3\)
180\(\pi + 18 \pi = 198cm^3\)
N.B h = r
V = \(\pi x (3)^2\) x 20 = \(\frac{2}{3} \times \pi \times (3)^3\)
180\(\pi + 18 \pi = 198cm^3\)
