Question

find the diameter of the object. diameter: \boxed{} cm

Explanation:

Step1: Recall diameter formula

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

Step2: Identify the radius

From the image, the radius \( r = 3.5 \) cm.

Step3: Calculate diameter

Substitute \( r = 3.5 \) into \( d = 2r \): \( d = 2\times3.5 = 7 \) cm.
