C is the correct answer if you look at your studies
There are numerous information's already given in the question. Based on the information's provided, the answer can be easily deduced.
Radius of the sphere = 7 meters
Value of pi = 3]
Then
Surface area of the sphere in question = <span>4πr^2
= 4 * 3 * (7)^2
= 12 * 49
= 588 square meters.
From the above deduction, we can conclude that the surface area of the sphere in question is 588 square meters.</span>
