Question

1. if a sphere has a diameter of 14 inches, what is its radius?

a. 28 inches
b. 21 inches
c. 7 inches
d. 14 inches

Explanation:

Step1: Recall the relationship between radius and diameter

The formula for the radius \(r\) of a circle (or sphere) in terms of the diameter \(d\) is \(r=\frac{d}{2}\).

Step2: Substitute the given diameter value

Given \(d = 14\) inches. Substitute into the formula: \(r=\frac{14}{2}\).

Step3: Calculate the radius

\(\frac{14}{2}=7\) inches.

Answer:

C. 7 inches
