Answer:
6
Step-by-step explanation:
We are doing unit rate.
Unit rate is when you get the value for 1 of the variables. In this, we would want to get the value for t. We do to find the t value. Now we do
to find the value of the missing t. T=6.

The choices are not attached but we can solve the problem from the given information
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
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
