A toy is in the form of a cone surmounted on a hemisphere. The diameter of the base and the height of cone are 6cm and 4cm. determine surface area of toy?
Given height of (h) = 4cm
Diameter of cone (d) = 6cm
Radius (r) = 6/2 = 3cm
Let ‘l’ be ***** height of cone
***** height of cone (l) = 5cm
Curved surface area of cone ( S1) = πrl
Curved surface area of toy =103.62cm2
