Question

the slant height of an icecream cone is12 cm and its curved surface area is 113.04 sq cm what is the radius of a base ok this cone ?(π= 3.14)

Answer 1

Let the radius of the cone be r cm.
Slant height = 12 cm.
C. S. A. of cone = 113.04 cm^2
Now,
C.S.A. of cone = pi * r * l
=> 113.04 = 3.14 * r * 12
=> 37.68 * r = 113.04
=> Radius of cone = 3 cm...


Hope it helps u.......
