Answer:
28π cm²
Step-by-step explanation:
The surface of a cylinder is given by the formula:
where r is the radius of the base, and h is the height.
Using the image, we can find that the radius of the cylinder would be 2 cm, and the height would be 5 cm.
Now, to find the surface area of the cylinder, we would have to plug in 2 for r (the radius of the base) and 5 for h (the height of the cylinder) into the formula for the surface area of a cylinder.
Now we plug in 2 for r and 5 for h for the equation for the surface area of a cylinder:
2π(2)(5) + 2π(2)² = 20π + 2π(4) = 20π + 8π = 28π
Remember, the radius and the height are given to us in cm, and w are solving for surface area, so the answer should be in cm² (square centimeters).
The surface area of the cylinder would be 28π cm².
28π cm² would be an exact answer. For the approximate answer, plug in 3.14 (most math classes use 3.14 to approximate π) for π.
I hope you find this helpful. :)

1.125
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
Let's solve your equation step-by-step.
6(x − 5) = 54
Step 1: Simplify both sides of the equation.
6(x − 5) = 54
(6)(x) + (6)(−5) = 54(Distribute)
6x + − 30 = 54
6x − 30 = 54
Step 2: Add 30 to both sides.
6x − 30 + 30 = 54 + 30
6x = 84
Step 3: Divide both sides by 6.
6x/6 = 84/6
x = 14
