"Question 1 Find the volume of the right circular cone with (i) radius 6 cm, height 7 cm (ii) radius 3.5 cm, height 12 cm
Class 9 - Math - Surface Areas and Volumes Page 233"
Answers
Right circular cone:
If a right angled triangle is revolved about one of the two sides forming a right angle keeping the other side fixed in position then the solid so obtained by segments is called right circular cone.
VOLUME:
The space occupied by an object solid body is called the volume of the particular object solid body volume is always measured in cubic unit.
==========================================================
Given:
(i)
Radius (r) = 6 cm
Height (h) = 7 cm
Volume of the right Circular cone = 1/3 πr²h
= (1/3 × 22/7 × 6 × 6 × 7)
= 22×12
= 264 cm³
Volume of the right Circular cone = 264 cm³
Given:
(ii) Radius (r) = 3.5 cm
Height (h) = 12 cm
Volume of the right Circular cone = 1/3 πr²h
= (1/3 × 22/7 × 3.5 × 3.5 × 12)
= 154 cm³
Volume of the right Circular cone= 154 cm³
