Question

The formula V=arh gives the volume of a cylinder with radius r and height h. Find the volume of a cylinder with radius (x + 4) cm and height 5 cm. Write your answer in standard form.​

Answer 1

V = a (x + 4)*5 but see below.

Explanation:

You're not going to get any kind of answer that gives V = 122 or some other pure number.

Formula

V = arh

Givens

a = pi * r

r = (x + 4)

h = 5cm

Solution

V = a * (x + 4)*5

or

V = pi * (x + 4)^2 * 5

There is no indication of which one to choose.
