Question

a cylinder has a radius of 2.8 inches and a height of 2.4 inches. which cylinder is similar?

Explanation:

Step1: Find the ratio of radius to height of given cylinder

$\frac{2.8}{2.4}=\frac{7}{6}$

Step2: Check ratios for each option

Option 1:

$\frac{1.8}{1.4}=\frac{9}{7}$

Option 2:

$\frac{1.4}{1.2}=\frac{7}{6}$

Option 3:

$\frac{5.6}{4.2}=\frac{4}{3}$

Option 4:

$\frac{2.4}{2.8}=\frac{6}{7}$

Answer:

The second cylinder (radius 1.4 in and height 1.2 in) is similar.
