Question

Find the volume of the cone shown as a decimal rounded to the nearest tenth. 22m 12m

Answer 1

829.4 m³

Explanation:

Volume of cone:

diameter = 12 m

r = 12 ÷ 2 = 6 m

h = 22 m

`\sf \boxed{Volume \ of \ cone =(1)/(3) \pi r^2h}`

`= (1)/(3)*(22)/(7)*6*6*22\\\\=(22)/(7)*2*6*22\\\\=(5808)/(7)\\\\= 829.4 \ m^3`
