36 pi = 113.09734 (rounded)(Since 'pi' is irrational and can never be written exactly, no sum, difference,product, or quotient that involves it [once] can be written exactly either.)
36 pi
The diameter is 36/pi
The volume of a cylinder can be expressed asV = (pi)r2hwhere V is the volume, r is the radius, and h is the height. (The variables stuck together mean to multiply)If the diameter of the cylinder is 24 in, then the radius is half of that, or 12 in.And the height (length) is 36 in.V = (pi)r2hV = (pi)(12)2(36)V = (pi)(144)(36)So now, the volume is officially 5,184 times pi, but if you want to approximate, it would be16,286.016 in3
d = 6
Because circumference c = Pi x diameter (36 x Pi) circumference = diameter = 36 therefore the radius = 36/2 = 18. or c = 2.Pi.r so r = c / 2.Pi therefore 36.Pi / 2.Pi = 18
circumference=pi*diameter so diameter=circumference/pi 36/pi=11.4591559
Circumference C=2*pi*r = 36 in. r = 36/(2*pi) = 18/pi in. Cylinder Volume V=pi*r2*h = pi*(18/pi)2*36 in3 = 182*36/pi in3 = 3712.8 in3 1 in3 = .004329 US gal 3712.8 in3 = 16.072 gal
pi x diameter gives you the circumference. pi x 36 = ? I don't have my calculator on me.
It is: 36*pi
Area of a circle is (pi)(R)2 .If diameter =12, then radius = 6,and Area = (pi)(6)2 = 36 pi .Full circle = 360 degrees.10 degrees = 10/360 = 1/36 of the full circle.Area of the sector ('slice') = (full area)/36 = (36 pi)/36 = pi = 3.142 square units (rounded)
An area cannot be 36 inches. However, assuming that the area was meant to be 36 SQUARE inches, then pi*r2 = 36 so r = sqrt(36/pi) = 3.39 inches.
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
Circumference = 36*pi
Circumference = 2 x pi x radius = pi x diameter where pi = 3.1416 Diameter = circumference / pi = 36/3.1416 = 11.46
Area of 12 inches diameter cylinder = pi.r2 = pi*62 = 36*pi square inches (r = radius = 6 inches). Volume = area * height = 36*pi*36 = 1296*pi = 4071.5 cubic inches (to nearest 1st decimal). (pi = 3.14159 to nearest 5th decimal).
