Answer:
The volume of cone = 448π m³
Explanation:
Points to remember
Volume of cone = (πr²h)/3
Where r - Radius of cone and
h - Height of cone
To find the volume of given cone
From the figure we can see,
Radius r = 8 m and Height h = 21 m
Volume = (πr²h)/3
= (π * 8² * 21)/3
= π * 64 * 7 = 448π
Therefore volume of cone = 448π m³
