Question

Volume of cone is 1212cm.cu. and its height is 24cm.Find the surface area of the cone.

Answer 1

Volume of cone = 1/3 x π r²h

h=24cm

Given volume=1212 cm³

*Therefore*

1212= 1/3 x 22/7 x R² x 24

48.20 = r²

7cm=r (approx.)

CSA cone=πrl

l²=r²+h²

l²=625cm

length=25 cm

CSA cone= 22/7 x 7 x 25

= 550 cm² *answer*
