Answer: Surface area = 68π inches²
Step-by-step explanation:
The formula for determining the total surface area of the circular cylindrical metallic rod is expressed as
Total surface area = 2πr² + 2πrh
Where
r represents the radius of the cylindrical rod.
h represents the height of the cylindrical rod.
π is a constant whose value is 3.14
From the information given,
Radius = 2 inches
Height = 15 inches
Therefore,
Surface area = (2 × π × 2²) + 2 × π × 2 × 15) = 8π + 60π
Surface area = 68π inches²

<h2>Hello!</h2>
The answer is: [-2,2]
<h2>
Why?</h2>
The range of a function shows where the function can exist in the y-axis.
To know the range of the function, we have to isolate x,
So

The only possible values that y can take go from -2 to 2. Taking values out of these values will give as result a non-real number.
Therefore,
The range of the function is [-2,2]

Step-by-step explanation:
hg=4
if correct then can we become friends
16x²=(4x)², 9=3², 24x=2*4x*3
so this is a perfect square: (4x+3)²
