What is the surface area of a sphere with a radius of 11 units?A.1331 units2B.363 units2C.726 units2D.484 units2SUBMITarrow_backPREVIOUS
Solution
The surface area of a sphere is given by the formula 4πr², where r is the radius of the sphere.
Given that the radius of the sphere is 11 units, we can substitute this value into the formula:
Surface area = 4π(11)² = 4π(121) = 484π units²
Therefore, none of the options A, B, C, or D are correct. The correct answer is 484π units².
