Question

The height of the cone is 15cm. if it's volume is 1570cm³,find the diameter of its base​

Answer 1

Answer:

10 cm

Step-by-step explanation:

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.
