George has a table tennis ball that is 4 centimeters in diameter What is the surface area of the ball?
A 4x square centimeters
B 8 square centimeters
C 161 square centimeters
D 32x square centimeters

A = approximately 12.6 cm^2p-by-step explanation:

The formula for the surface area of a ball of radius r is A = 4(pi)r^2.  Here the diameter is 4 cm, so the radius must be 2 cm.  Thus, the area of this table tennis ball is A = 4(3.14)(2 cm)^2, or A = approximately 12.6 cm^2
