Solve the problem.The function A(r) = 4?r2 gives the surface area of a sphere. Find A(1) and interpret. Round to the nearest hundredth, if necessary.the area when the radius is 1 in.
A. A(1) = 37.7; The value of A(1) is the surface area, in square units when the radius is 1 unit(s). B. A(1) = 12.57; The value of A(1) is the measure of the radius when the surface area is 1 square unit(s). C. A(1) = 37.7; The value of A(1) is the measure of the radius when the surface area is 1 square unit(s). D. A(1) = 12.57; The value of A(1) is the surface area, in square units when the radius is 1 unit(s).
