What is the decimal equivalent of the diameter if the radius of a piece of round stock is 7/32?

To find the decimal equivalent of the diameter when the radius is given, you first need to understand the relationship between radius and diameter. The diameter is twice the radius.

In this instance, the radius of the round stock is 7/32. To calculate the diameter, you multiply the radius by 2:

[

\text{Diameter} = 2 \times \left(\frac{7}{32}\right)

]

This calculation can be simplified as follows:

[

\text{Diameter} = \frac{14}{32}

]

To convert the fraction 14/32 into a decimal, you can perform the division:

[

\frac{14}{32} = 0.4375

]

As a result, the decimal equivalent of the diameter when the radius is 7/32 is 0.4375. This value corresponds with the correct choice, confirming that option B is indeed the right answer.
