how do i find the lentgh of the radius given the volume and height useing 3.14 example v=314ft3 h==25 ft
Please show me how to do it
Are you talking about a cylinder?
If so,
V = pi*r^2*h
314 = 3.14 r^2 * 25
100/25 = r^2
r = sqrt 4 = 2 feet
Just set up you equation and plug in what numbers you know.
Volume = pi x r^2 x height
314 = 3.14 x r^2 x 25
multiply on the same side of the =
314 = 78.5 x r^2
now, divide both sides by 78.5 to get the variable by itself
Finally, take this small, easy to work with number and find its square root!
Hope this helps!
To find the length of the radius, given the volume and height, you can use the formula for the volume of a cylinder:
V = π * r^2 * h
In this formula, V represents the volume, r represents the radius, and h represents the height. However, in the given example, we have the volume and height but we need to find the radius.
Let's rearrange the formula to solve for the radius:
V = π * r^2 * h
Divide both sides of the equation by (π*h):
V / (π * h) = r^2
Take the square root of both sides of the equation to solve for r:
√(V / (π * h)) = r
Now, let's substitute the values from the example into the equation:
V = 314 ft^3
h = 25 ft
π = 3.14
Now, we can plug in these values to calculate the radius:
r = √(314 / (3.14 * 25))
r = √(10 / 1)
r = √10
r ≈ 3.16 ft
Therefore, the length of the radius, given the volume of 314 ft^3 and height of 25 ft, is approximately 3.16 ft.
