Answer: scale factor = 1.5

Step-by-step explanation:

\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Side length of original figure}}

Given: Triangle ABC is a scaled copy of triangle DEF.

Side AB = 12 cm and is the longest side of ABC.

Side DE = 8 cm and is the longest side of DEF.

\text{For similar triangles, Corresponding sides are proportional.}

AB is corresponds DE (longest side of both triangles)

So, \text{Scale factor}=\dfrac{\text{AB}}{\text{DE}}=\dfrac{12}{8}=1.5

Hence, the scale factor = 1.5.

Find the volume of a cylinder with a radius of 4 in and a height that is 3 times the radius
german

Answer:

Volume of a cylinder: V = π * r² * h ,

Base surface area of a cylinder: A_b = 2 * π * r² ,

Lateral surface area of a cylinder: A_l = 2 * π * r * h ,

Total surface area of a cylinder: A = A_b + A_l ,

Step-by-step explanation:

So, when the radius is tripled, the volume will be 3 squared = 9 times than the previous one.
