$\huge \fbox \red{❥ Question}$



A wooden toy was made by scooping out a hemisphere of same radius from each end of a solid cylinder. If the height of the cylinder is 10 cm, and its base is of radius 3.5 cm, find the volume of wood in the toy. [Use π = 22by7] ​

Answer 1

Answer:

Volume of cyclinder=pi r2h

h=10cm

r=3.5cm

volume of wooden toy=22÷7×(3.5)2×10

=385cm3

Answer 2

Step-by-step explanation:

Given height of cylinder =10 cm 

Radius of cylinder =3.5 cm

The volume of toy= Volume of cylinder −2×Volume of a hemisphere

                       =πr2h−(2×32πr3)

                       =[π(3.5)2×10]−(2×32×π(3.5)3)=205.251 cm3
