Question

radius = \frac{1}{2} the diameter
what is the radius of a circle
with a 6.2 cm diameter?

Explanation:

Step1: Use the formula for radius

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

Step2: Substitute the given diameter value

Given \( d = 6.2\) cm. Substitute \( d = 6.2\) into the formula \( r=\frac{d}{2}\), so \( r=\frac{6.2}{2}\).

Step3: Perform the division

\( \frac{6.2}{2}=3.1\).

Answer:

\( 3.1\) cm
