Question

current skill a circles radius is 13 millimeters. what is the circles area? use 3.14 or a calculator button for pi and provide an answer accurate to the nearest tenth. r = 13 mm label required

Explanation:

Step1: Recall circle area formula

The area of a circle is $A = \pi r^2$

Step2: Substitute $r=13$, $\pi=3.14$

$A = 3.14 \times 13^2$

Step3: Calculate $13^2$ first

$13^2 = 169$

Step4: Compute the product

$A = 3.14 \times 169 = 530.66$

Step5: Round to nearest tenth

$530.66 \approx 530.7$

Answer:

$530.7$ square millimeters
