Question

find the volume of a cone whose base area is 300sq.cm and height is 15cm​

Answer 1

Step-by-step explanation:

base area of cone, πr² = 300cm²

height of cone, h = 15m

volume of cone =

$= \frac{\pi \: {r}^{2} \: h }{3} \\ = \frac{ ( \pi \: {r}^{2}) \: h}{3} \\ = \frac{(300)(15)}{3} \\ = 100 \times 15 \\ 1500 \: {cm}^{3}$

the volume of a cone is 1500cm³
