Answer

$\boxed{\text{The radius of the circle is 42 cm}}$

Steps

Step 1 ：The diameter of the circle is given as $84 \mathrm{cm}$.

Step 2 ：The radius of a circle is half of its diameter. So, to find the radius, we need to divide the diameter by 2.

Step 3 ：Using the formula $\text{radius} = \frac{\text{diameter}}{2}$, we substitute the given diameter into the formula.

Step 4 ：$\text{radius} = \frac{84}{2} = 42$

Step 5 ：$\boxed{\text{The radius of the circle is 42 cm}}$
