The surface area of sphere of radius 5 cm is 5 times to curved surface area of cone of radius 5 cm. find the height of cone. anyone can solve this problem

Answers

Surface area of sphere = 4πr^2 =100 πcm^2
curved surface area of cone = πrl 4πl
ATQ, surface area of sphere=5× curved surface area of cone100π=4πl× 5100=20l5= slant height (l)
l^2=r^2+ h^25^2=4^2+h^225=16+ h^225—16=h^29=h^23=height
volume of cone= 1/3πr^2h = 352/7 50.28
