Answer:. Hey mate ❤️❤️.....here u go

surface area of sphere=5(curved surface area of cone)

4πr^2 = 5(πRl)

4r^2 = 5Rl

4(5)^2 = 5(4)l

l= 5cm

now...

as we know, in cone

r^2+h^2=l^2

h^2 = 9

h= 3cm

now, volume of the cone

= 1/3πR^2h

= 50.28cm^3

hope it works❤️

plz mark it as brainliest answer
