Question

A toy is in the form of a right circular cylinder with a hemisphere on one end and a cone on the other. The height
and radius of the base of the cylindrical part are 13 cm and 5 cm respectively. Radius of the hemisphere and
radius of the conical part are the same as that of the cylinder. The height of the conical part 12 cm. Find the
surface area of the toy.

Answer 1

Hey rkelectronik what’s the answere

Answer 2

hope it is helpful to 2

surface area of toy = sa of cylinder + sa of cone + sa of hemisphere =

= 2πrh + πrl + 2πr sq

= πr( 2 × 13 + 13 + 2) = 22/ 7 × 5 ( 41) = 22/ 7 × 205

= 4510 / 7 is the correct answer

hope it can be solved
