The two point formula :
The points are (-2, 1) and (1, 10)
Using the formula above :
The answer is 3x - y = -7
Answer:
Step-by-step explanation:
The volume of a cylinder is given by :
.....(1)
Where
r and h are the radius and the height of the cylinder.
We need to solve the equation of r. Cross multiplying both sides in equation (1).
Dividing both sides by . So,
So, the radius of the cylinder is equal to .
