The radius is 10 units, and each layer is one unit high. What is the volume of the cylinder in cubed units?​
alexandr1967 [171]

Answer:

Volume of cylinder is 6285.71 square units.

Step-by-step explanation:

Given the radius of cylinder 10 units. The height is twice its radius. we have to find its volume.

r=10 units

⇒ Diameter, d = 20 units

Also given height is twice its radius.

⇒ Height=2(r)=2(10)=20 units

<h2><em><u>Volume of cylinder=πr^2h</u></em></h2>

= 22/7 × 100×20

=22/7 × 2000

= 44000/7

= 6285.71square units.

hence, volume of cylinder is 6285.71 square units.

the function of y= x^2 - 4x + 8 approximates the height y, of a bird and its horizontal distance, x as it flies from one fence p
Vika [28.1K]
Rewrite the given equation as 
y=x^2-4x+8=x^2-4x+4+4=(x-2)^2+4.
Since (x-2)^2\ge 0, you can conclude that the imimum value of y will be gained for the minimum value of (x-2)^2. The minimum value of (x-2)^2 is 0 for x=2. 
So, y(2)=0+4=4.
Answer: minimum value of y is 4, when x=2.
