If you have a cylinder with a radius of 3cm and a height of 12cm how do you find the circumference of the cylinder?
2(pi)r=2X3.14X3cm=18.85cm to four significant figures
What is the formula to get pi?
Take the circumference of a circle and divide it by the diameter of that circle: ∏=C/D
What is the formula for finding the surface area of a cylinder?
The surface area of a cylinder can be found using the following formula - SA = 2(Pi*r2) + (2*Pi*r)*(H) Pi = Approximately 3.14 r = Radius of the base of the cylinder H = Height of the cylinder
Formula for finding the area of a cylinder?
2 pi r h
What is the radii of a circle?
The radius(radii is the plural) of the circle is half the distance of circle's diameter. The formula is r=(1/2)diameter.
What is the formula for finding the area of base of a cylinder?
The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)
How do you find an experimental value of pi?
The ratio of C to D will equal pi. This is based on the known formula for the circumference of a circle. D = Diameter of the circular base of a cylinder (independent) C = Circumference of the circular base of a cylinder (dependent)
What is the circumference of a cylinder 16 in diameter and 15cm height?
The cylinder's circumference is approximately 50.27cm
What is the formula of a circumference?
circumference=r2pi
Why the formula of circumference of circle always constant?
Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter
What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
How do you determine the circumference of a circle if you know the radius?
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
What is the circumference of a cylinder that is 8.5 wide and 11 in height?
The circumference of a cylinder is not dependent on its height, It's simply how far it is round it. So it's the usual formula of 2pi x r. or 3.142 x 2 x 4.25 = 26.707 of the units you have chosen but not mentioned (inches, cms, mms?).
What is the volume of a cylinder when the length is 9 and the circumference is 12.56?
The volume of a cylinder with a length of 9 and a circumference of 12.56 is: about 113 cubic units.
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
What is the circumference of a cylinder 8 diameter and 12 in height?
The circumference is about 25.13 units.
Why do you need a measuring cylinder?
measure liquids or the area/circumference of the cylinder.
