Question

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

Answer 1

Answer:

829.4 m³

Step-by-step explanation:

Volume of cone:

        diameter = 12 m

                     r = 12 ÷ 2 = 6 m

                     h = 22 m

$\sf \boxed{Volume \ of \ cone =\dfrac{1}{3} \pi r^2h}$

                           $= \dfrac{1}{3}*\dfrac{22}{7}*6*6*22\\\\=\dfrac{22}{7}*2*6*22\\\\=\dfrac{5808}{7}\\\\= 829.4 \ m^3$
