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:
the length of the first side of the triangle is
the length of the second side of the triangle is
the length of the third side of the triangle is
Step-by-step explanation:
Let
x-----> the length of the first side of a triangle
y----> the length of the second side of a triangle
z---> the length of the third side of a triangle
we know that
-----> equation A
-----> equation B
The perimeter of the triangle is equal to
so
-----> equation C
substitute equation A and equation B in equation C
solve for x
Find the value of each side
the first side of a triangle is x
the second side of a triangle is y
the third side of a triangle is z
