Question

the radius of a circle is 1 millimeter. what is the circles area?
round your answer to the nearest hundredth.
______ square millimeters

Explanation:

Step1: Recall circle area formula

The area of a circle is given by $A = \pi r^2$, where $r$ is the radius.

Step2: Substitute radius value

Substitute $r = 1$ mm into the formula:
$A = \pi (1)^2 = \pi$

Step3: Calculate and round to hundredth

Approximate $\pi$ to the nearest hundredth: $\pi \approx 3.14$

Answer:

3.14 square millimeters
