By selling a laptop for €1150, a store makes a profit of 25%. (i) What did the store pay for the laptop?
(ii) At what price should the laptop be sold to make a profit of 20%?

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!
