Question

the diameter of a circle is 34.2 millimeters. what is the circles area? round your answer to the nearest hundredth. square millimeters

Explanation:

Step1: Calculate the radius

Radius $r = \frac{\text{diameter}}{2} = \frac{34.2}{2} = 17.1$ mm

Step2: Apply circle area formula

Area $A = \pi r^2 = \pi \times (17.1)^2$

Step3: Compute and round result

$A = \pi \times 292.41 \approx 918.63$

Answer:

918.63 square millimeters
