Question

the figure is made of up of a cone and a cylinder, to the nearest whole number what is the approximate volume of this figure. PLEASE HELP FAST

Answer 1

The total volume is the sum of volume of cone and volume of cylinder.

Volume of cylinder = πr²h
π = 3.14
r = 4/2 = 2 mm
h = 2 mm

So, volume of cylinder equals:


`3.14 *(2)^(2)*2 =25.12` mm³

Volume of cone =
`(1)/(3) \pi r^(2)h`
π = 3.14
r = 2 mm
h = 3 mm

So, volume of cylinder equals:


`(1)/(3)*3.14* (2)^(2)*3=18.84`mm³

Thus, total volume of the figure = 25.12 + 18.84 = 43.96 mm³
