Tyler cuts out a cardboard circle with a radius and stacks them to make the shape of a cylinder five centimeters high. what is the approximate volume of the cylinder

Don't get confused with the language of the question. The cylinder was made by stacking cut  pieces of cardboard in circular shape. It is also given that the radius of circle is unit(1). 
Volume of cylinder = πr²h = 3.14×1²×5 = 15.7 cm³

Answer: b 2 = 1.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

therefore, b 2= 1.
