Volume of Cone
Volume of the right circular cone is 248.7 m³
Step-by-step explanation:
A right circular cone is a three dimensional geometrical object. Right circular cone is a circular cone whose axis is perpendicular to its base. The slant height is the length of an element. All elements of a right circular cone are all equal.
The volume of the right circular cone is defined as 
where r is radius of the cone and h is the height of the cone
V = 
Given diameter d = 8.9 m
So the radius r = 8.9 ÷ 2 = 4.45 m
V = (1/3) × 3.14 × (4.45)² × 12
= (1/3) × 3.14 × 19.80 × 12
= 248.69 m³
Hence the Volume of the right circular cone is 248.7 m³
