The correct answer is 3,632 m2.
The formula for the surface area of a sphere is A = 4πr^2.
Given that the diameter of the sphere is 34 meters, the radius (r) would be half of the diameter, so r = 34/2 = 17 meters.
Plugging the radius into the formula, we get A = 4π(17)^2 = 4π(289) = 1,156π ≈ 3,632 m2.
