A Toy is in the form of a hemisphere surmounted on a cylinder of height 10cm as shown in the figure. If the radius of the cylinder is 3.5cm find the volume of the toy.
Answers
Answer:
volume of the toy = 474.84
Step-by-step explanation:
Given A toy is in form of a hemisphere surmounted on cylinder
Height of the cylinder h = 10 cm
radios of the cylinder r = 3.5 cm
radios of the cylinder will be the radios of the hemisphere
⇒ volume of the toy = volume of hemisphere + volume of cylinder
⇒ volume of the hemisphere =
=
=
=
= 89.84
⇒ volume of the cylinder =
=
= 11(3.5)(10)
= 385
∴ total volume of the toy = 89.84 + 385
= 474.84
