Question

37. A toy is made in the shape of a cylinder with one hemisphere stuck to one end
and a cone to the other end, as shown in the figure, the length of the cylindrical
part of the toy is 20cm and its diameter is 10cm. If the slant height of the cone
is 13cm. Find the surface area of the toy.
13cm
10cm
20cm​

Answer 1

Answer:

Given,length of cylindrical part=20cm Diameter=10cm

So, Radius=10/2cm = 5cm

Radius of hemispherical part=5cm

Radius of conical part=5cm

Slant height=13cm

So, Surface area of the toy

Hence, surface area of the toy is 990 cm^2.
