Answer:
The expression can be used to find h is
The height of the cone is cm
Step-by-step explanation:
The formula of the volume of the cone is V = π r² h, where
- r is the radius of its base
- h is the height of it
Let us find the height of the cone from the formula of its volume
∵ V = π r² h
- Multiply both sides by 3
∴ 3 V = π r² h
- Divide both sides by π r²
∴
- Switch the two sides
∴
The expression can be used to find h is
∵ The radius of the cone is 7 cm
∴ r = 7
∵ The volume of the cone is 147 cm³
∴ V = 147
- Substitute them in the expression of the height to find it
∵
∴ h = cm
The height of the cone is cm
Answer:
So we can express the radius in terms of the hours elapsed like this:
And the reason of this is because each hour the radius increase 6.5 inches, and if we replace in the formula of area we got:
And this function would represent the area of the circle as function of the hours elapsed,
Step-by-step explanation:
For this case we know the radius of a circle given and we also know the incresing rate for the radius:
And we want to express the are of the circle A as a function of h = the number of hours elapsed.
We know that the area of a circle is given by:
So we can express the radius in terms of the hours elapsed like this:
And the reason of this is because each hour the radius increase 6.5 inches, and if we replace in the formula of area we got:
And this function would represent the area of the circle as function of the hours elapsed,
