Question

what is the surface area of this sphere?
round your answer to the nearest hundredth.
6 in
square inches

Explanation:

Step1: Identify diameter and radius

The diameter is 6 in, so radius $r = \frac{6}{2} = 3$ in.

Step2: Apply surface area formula

Surface area of sphere: $4\pi r^2 = 4\pi(3)^2 = 36\pi$

Step3: Calculate numerical value

$36\pi \approx 36 \times 3.1416 = 113.0976$

Step4: Round to nearest hundredth

$113.0976 \approx 113.10$

Answer:

113.10
