Question

Find the volume of the right circular cone with radius 3.5cm height 12cm ​

Answer 1

Step-by-step explanation:

1/3 πr²h

= 1/3 x 22/7 x 35/10 x35/10 x 12

= 11 x 7 x 2

= 154cm³

Answer 2

Answer:

$\\ \sf \: Volume = \frac{1}{ 3} \: \pi \: {r}^{2} \: h \\ \\ \\ \implies \sf \: \frac{1}{3} \times 3.5 \times 3.5 \times 12 \\ \\ \\ \implies \sf \: 154 \: {cm}^{3}$
