1.	The slant height of a cone is15cm long if the diameter of the base of the cone is8cm calculate the volume of the cone
Answer» ANSWER: 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: Height (H) = 15 cm Volume = 1570 cm³ Let the radius of the base of cone be r cm Volume of a cone=1/3 πr²h Volume = 1570 cm³ 1/3 πr²h = 1570 1/3×3.14×r² ×15 = 1570 r²= 1570/(3.14×5) = 15700/157= 100 r²=100 r=√100=10 r = 10 cm Hence, Radius of the base is 10 cm.

Answer»

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:

Height (H) = 15 cm

Volume = 1570 cm³

Let the radius of the base of cone be r cm

Volume of a cone=1/3 πr²h

Volume = 1570 cm³

1/3 πr²h = 1570

1/3×3.14×r² ×15 = 1570

r²= 1570/(3.14×5)

= 15700/157= 100

r²=100

r=√100=10

r = 10 cm

Hence, Radius of the base is 10 cm.
