true

Step-by-step explanation: they are all equivalent

x=2 & x=1

step-by-step explanation:

7*1=7

7*2=14

7 is less than 21

14 is less than 21

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!
