Question

The surface area of a sphere of radius 5cm is 5times the area of the curved surface of a cone of radius 4cm. Find the hieght and the volume of the cone.

Answer 1

Step-by-step explanation:

4π(5)^2=5×π×4×l

25= 5l

l=5

heigt of cone=√(25-16)

height of cone =3cm

volume of cone= 1/3×3.14×16×3

=3.14×16 =50.24cm^2,

Answer 2

Answer:

4π(5)^2=5×π×4×l

25= 5l

l=5

heigt of cone=√(25-16)

height of cone =3cm

volume of cone= 1/3×3.14×16×3

=3.14×16 =50.24cm^2,
