Please answer this correctly I have to finish this today. I want genius people or expert people to answer this correctly without making mistakes

Surface Area is 16π mm²

Step-by-step explanation:

Remember me? (I answered your question before) Do I count as "genius people or expert people"? I certainly hope so.

The area for a cylinder's surface area is

a=2πrh+2πr²

The cylinder base's radius is 2 mm

The cylinder's height is 2 mm

Putting into the equation:

a=2×π×2×2+2×π×2²

a=2π×2×2+2×π×2²

a=4π×2+2×π×2²

a=8π+2×π×2²

a=8π+2×π×4

a=8π+2π×4

a=8π+8π

a=16π

The surface area of the cylinder is 16π mm².

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
