A joker’s cap is in the form of a right circular cone of base radius 7 cm and height 24 cm. Find the area of the sheet required to make 10 such caps

Radius (r) = 7cm

Height (h) = 24 cm


Slant height (l) =


=


= 25m


CSA (1 conical cap) =


= ( * 7 * 25)


= 550 cm2


CSA of 10 conical caps = (10 × 550)


= 5500 cm2
