Question

what is the surface area of this sphere?
round your answer to the nearest hundredth.
5.6 mm
square millimeters

Explanation:

Step1: Recall surface area formula for sphere

The formula is $SA = 4\pi r^2$, where $r$ is the radius.

Step2: Substitute radius value

Here, $r = 5.6$ mm. So $SA = 4\pi (5.6)^2$.

Step3: Calculate $5.6^2$

$5.6^2 = 31.36$.

Step4: Multiply by 4π

$SA = 4 \times \pi \times 31.36 = 125.44\pi \approx 125.44 \times 3.1416 \approx 394.08$.

Answer:

394.08
