A 4:1 scale drawing of a bearing is shown on an A-size print. Using a ruler, you measure the inside diameter of the part on the

Pani-rosa [81]

Answer:

A. 6.0

Step-by-step explanation:

We have been given that the the inside diameter of the part on the paper is 1.50 inches.

We have been given that scale is 4:1 for actual size to drawing side.

$\text{Scale}=\frac{\text{Actual size}}{\text{Map size}}=\frac{4}{1}$

Upon substituting 1.50 in our given proportion, we will get:

$\frac{\text{Actual size}}{1.50\text{ inches}}=\frac{4}{1}$

$\frac{\text{Actual size}}{1.50\text{inches}}\times 1.50\text{ inches}=\frac{4}{1}\times 1.50\text{ inches}$

$\text{Actual size}=4\times 1.50\text{ inches}$

$\text{Actual size}=6.0\text{ inches}$

Therefore, the actual size is 6.0 inches and option A is the correct choice.
