Step-by-step explanation:
Given:-
RADIUS OF SPHERE:-5cm
RADIUS OF CONE:-4cm
curved surface area of cone=5(surface area of sphere)
where, r1 is radius of sphere.
l is slant height of cone.
r is radius of cone.
We know that from Pythagoras theorem,
by inserting values given we get,
Now by formula of volume of cone we get,
Hope it helps you.
