Which expression is a factor of n^2 + 3m - 54? answer choices: n + 6 n^2 + 9 n - 9 n + 9

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!

answer: f = 32.2m

step-by-step explanation: that is the answer
