Question

find the radius of the button.
28 mm
radius:
mm

Explanation:

Step1: Recall the formula for radius

The diameter \( d \) of a circle is related to the radius \( r \) by the formula \( r=\frac{d}{2} \).

Step2: Identify the diameter

From the image, the diameter of the button (circle) is \( 28 \) mm.

Step3: Calculate the radius

Substitute \( d = 28 \) mm into the formula: \( r=\frac{28}{2}=14 \) mm.

Answer:

14
