The height and diameter of a cylindrical cup are the same length. The volume of the cup is 54pi in3 what is the radius and the h
ASHA 777 [7]

Answer:

The radius of the cup is 3\ in and

the height of the cup is 6\ in

Step-by-step explanation:

we know that

The volume of the cylinder is equal to

V=\pi r^{2}h

Let

x-----> the height and the diameter of the cylinder

we have

V=54\pi\ in^{3}

h=x\ in

D=x\ in

r=(x/2)\ in

substitute the values

54\pi=\pi (x/2)^{2}(x)

simplify

54=(x/2)^{2}(x)

54=\frac{x^{3}}{4} \\ \\x^{3}=216\\ \\x=6\ in

therefore

The radius of the cup is

r=(6/2)=3\ in

The height of the cup is

h=6\ in
