If fx=2 and g(x)=2x show its a constant​

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 for #1 is c

answer for #2 is d

can i get brainliest

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
