Answer:
13.09 pounds, 13,10 pounds if you have to round, which is not clear (result is 13.095).
1/4 - 1/2 = -1/4 but 1/2 - 1/4 = 1/4
The formula for the height of a cylinder is h = V / (π.r²) and the height of a cylinder with a volume of 36 cm³ and a radius of 3 cm is 4/π cm
Given a cylinder with a radius r and height h, then its volume is given by the formula:
V = π.r².h
Where:
V = volume
r = radius
h = height
To find the formula for the height, divide both sides by π.r²
V : π.r² = π.r².h : π.r²
or,
h = V / (π.r²)
The given parameters are:
V = 36 cm³
r = 3 cm
Substitute those parameters into the formula:
h = 36 / (π.3²)
h = 36 / (9π)
h = 4/π cm
