Question

the shape of the toy is a cylinder of radius 5 cm and height 8 cm on top of a hemisphere of radius 5cm calculate the volume of a toy

Answer 1

889.66 cm^3

Explanation:

here's your solution

=> radius of cylinder = 5 cm

=> height of cylinder => 8 cm

=> radius of hemisphere = 5 cm

=> volume of toy = ( vol of cylinder + vol of hemisphere)

=> volume of cylinder = πr^2h

=> putting value , = 22/7*5*5*8

=> volume = 628 cm^3

=> volume of hemisphere = 2/3πr^3

=> putting value , = 2/3*22/7*5^3

=> volume of hemisphere = 261.66 cm^3

=> volume of toy = (628 + 261.66)cm^3

=> volume = 889.66 cm^3

hope it helps
