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. PL

Deffense [45]

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 = $\frac{1}{3} \pi r^{2}h$
π = 3.14
r = 2 mm
h = 3 mm

So, volume of cylinder equals:

$\frac{1}{3}*3.14* (2)^{2}*3=18.84$ mm³

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