PLEASE HELP BRAINLIEST

Step-by-step explanation:

The surface area of this cylinder consist of two circles and a 3D outer edge with respect to the circumference. The area of a circle is given as . Using as requested in the problem, the area of both these circles is:

.

The 3D outer edge is then .

The area of this 3D outer edge is represented by . Therefore, we set up the following equation:

.

(4,5

look up a corrdinate plane and do what the thingy says and boom

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
