Which of the following are equivalent to the function y=3cosx+2? check all that apply. a. y=3sin(x-π/2)+2
b. y=-3cosx-2
c. y=3sin(x+π/2)+2
d. y=3cos(-x)+2

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
