Question

Sent question in picture form and wanted to no what to do

Answer 1

The rule of the volume of the cone is

`V=(1)/(3)*\pi* r^2* h`

r is the radius

h is the height

Since the height of the given cone is 11 mm, then

h = 11

Since the radius of it is 4 mm, then

r = 4

Use pi = 3.14

Then substitute these values in the rule above

`\begin{gathered} V=(1)/(3)*3.14*4^2*11 \\ V=(1)/(3)*3.14*16*11 \\ V=184.21333333mm^3 \end{gathered}`

Round it to the hundredth (2 d.p)

`V=184.21mm^3`

The volume of the cone is 184.21 cubic mm
