Armani · Answer 1

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 = 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.
