Answer:
189
Step-by-step explanation:
Since the series is geometric with common ratio r, then
r = 6 ÷ 3 = 2
The terms in the series are twice the previous term, that is the series is
3 + 6 + 12 + 24 + 48 + 96 ← summing the terms gives
sum = 189
<span>Cone Volume = (<span>π<span> • r² •<span> h) ÷ 3
</span></span></span></span>
Cone Volume = (<span>π * 5^2 * 6) / 3
</span>Cone Volume = (<span>π * 25 * 6) / 3
</span>Cone Volume = (<span>π * 25 * 2)
</span>Cone Volume = 50 * PI
