You need a 60% alcohol solution. on hand, you have a 30 ml of a 45% alcohol mixture. you also have 65% alcohol mixture. how much of the 65% mixture will you need to add to obtain the desired solution? you will need ml of the 65% solution and of the desired 60% solution.

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!
