Answer:

Step-by-step explanation:

∆ABC is similar to ∆DEF if and only if the ratio of their corresponding side lengths are the same.

Let's find out:

DE/AB = 10/5 = 2

EF/BC = 8/4 = 2

FD/CA = 12/6 = 2

The ratio of their corresponding side lengths are equal, therefore, ∆ABC is similar to ∆DEF based on the SSS Similarity Theorem.

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) c

marishachu [46]

Answer:

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

Step-by-step 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

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

There is no indication of which one to choose.
