A computer store buys a computer system at a cost of $468.60. The selling price was first at $ 781, but then the store advertised a 30 % markdown on the system. Find the current sale price.

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!

ratio is 2 : 9

the answer is three

13.5 : 3
