Answer:
c.
314 sq. cm
Step-by-step explanation:
Surface area of sphere:
The surface area of an sphere with radius r is given by:
[tex]S = 4\pi r^2[/tex]
Find the surface area of a sphere with a diameter 10 cm.
Radius is half the diameter, so [tex]r = \frac{10}{2} = 5[/tex]
The surface area is:
[tex]S = 4\pi*5^2 = 100\pi = 314[/tex]
314 square centimeters, and option c is the answer.
