Question

The surface area of a sphere of radius 5 cm is five times the area of the curved surface of a

cone of radius 4 cm. Find the height and the volume of cone (take π = 22/7).​

Answer 1

Answer:

50.29 cm^3

Step-by-step explanation:

Surface area of sphere = 5( CSA of cone)

4*pie*r1^2 = 5*pie*r*l

L=5cm

(pie and pie gets cancelled)

h^2=l^2-r^2

5^2-4^2

9

h=9cm

substitute the values of the above answers in the formula for the volume of cone

you will get

volume= 50.29 cm^3
