Answer:
Radius(r)=7cm
Slant height(l)=25cm
Vertical height(h)=√25^2-7^2
=√625-49
=√576
=24cm
Volume=1/3πr^2
=1/3*22/7*7^2
=51.33cm^3

Step-by-step explanation:
Given :
Radius = 7 cm.
Slant height (l) = 25cm.
Formula :
Height = √l^2-r^2
Volume of Right circular Cone=1/3*π*r^2 *h
Solution:
Height (h) = √25^2-7^2 = √625-49
= √576
= 24 cm.
Volume = 1/3 ×22/7 × 7× 7 × 24
= 22 × 7 × 8
= 1232 cm. Cube
