Answer:
Step-by-step explanation:
There was no figure but the question is clear
Volume of a cylinder is given by the formula
where r is radius of base of cylinder, h is the height
Volume of a cone is given by
where r is the radius of base of cone, h is the height
The radius of the cylinder = (diameter) = (12) = 6cm
Height of cylinder = 15cm
Volume of cylinder
Radius of cone = (radius of cylinder) = (6) = 3 cm
Height of cone same as height of cylinder = 15cm
Volume of cone,
Difference is the volume of the remaining solid
We have
Plug in
:
⇒
So we now have
Plug in
:
⇒
⇒
which is approximately 2.874
So we get
or, in decimal form,
A + 2c - 5b - c + a - b
We're gonna have to combine like terms.
(a+a)+(-5b-b)+(2c-c)
2a-6b+c This is your answer
