Question

if the base area of a cone is 154 cm and its vertical height is 15 cm find its volume

Answer 1

πr^2=154 cm^2
r^2=7 cm

volume=1/3×22/7×7×7×15=770 cm^3

therefore it's volume is 770 cm^3.

Hope this will help you.

Answer 2

hiii!!!

here's ur answer...

given base area of the cone is 154cm²

as we know that the base of the cone is in circle shape.

therefore πr²=154cm²

and height of the circle is 15cm.

$volume \: of \: cone = \frac{1}{3} \times \pi {r}^{2} h \\ = \frac{1}{3} \times 154 \times 15 \\ = 154 \times 5 \\ = 770 {cm}^{3} \\ \\ hence \: the \: volume \: of \: the \: cone \: is \: 770 {cm}^{3}$

hope this helped u!!
