46.08 cm³
Ok, so we know:
Diameter = 4
Height = 11
Diameter = Radius²
the formula we need to use : pi × r² or (diameter) × height/3
We can substitute the height and the r² because we already know them.
So now, the equation we are using is : pi × 4 × 11/3
11/3 is about 3.666666666666666666666666 so on
If we multiply that by 4 in a calculator that will be 14.66666666666666666666 so on
Now multiply 14.666666666666666666666 so on in a calculator with pi
you will get 46.0766922527. If we round to the nearest hundredth it will be 46.08³
Answer:
46.06 cm.³ (it's not exactly the first answer so the fourth may be your best bet but it's your call :) )
Step-by-step explanation:
First, the formula of the volume of a cone is V = πr²(h/3). So, let's proceed by identifying the variables we were given in the diagram.
h = 11 cm.
Remember that d (diameter) is equal to 2r (twice the radius) so r = d/2 = (4cm)/2 = 2 cm.
r = 2 cm.
Now, we can plug these values into the formula for area.
V = πr²(h/3)
V = π(2cm)²(11cm/3) = (3.14)(4cm²)(11cm/3) = 46.06 cm.³
So the answer is 46.06 cm.³.
