There is a cylinder with a height of 8 units and a volume of 72 cubic units. What is the radius of the cylinder?
1 answer:
Answer:
Radius of the cylinder = 1.69 units
Step-by-step explanation:
Volume of a cylinder is given by the expression,
Volume = Area of the circular base × Height of the cylinder
Area of the circular base = πr²
Here, r = Radius of the circular base
Volume of the cylinder = πr²h
By substituting the values given in the question,
72 = π(r)²8
r² =
r² = 2.865
r = 1.692
r = 1.69 units

Answer:
(-1/4, 2)
Step-by-step explanation:
Substitute the given information into the equation and solve for y.
3y +4(-1/4) = 5
3y -1 = 5 . . . . . . simplify
3y = 6 . . . . . . . . add 1
y = 2 . . . . . . . . . divide by 3
The point is (-1/4, 2).
