The volume of a cylinder is equal to Pi times the square of the radius times the height of the cylinder. Pi*r2*h. Pi*r2 is the area of the base of a cylinder. The surface area of a cylinder is 2*Pi*r2+Pi*2r*h. 2*Pi*r2 is the area of the base of the cylinder times two to account for both bases. Pi*2r*h is the circumference of the base times the height of the cylinder
In math terms, pi, means 3.14, which is a everlasting decimal, that is just rounded to make your math easier. So pi, means 3.14 in math terms.
Total surface area including the two end pieces = (2*pi*radius2)+(2*pi*radius*height) in square units.
Leaving in terms of pi means, through out the whole answer you have the pi symbol when you sub and compute. So basically heres an example: 2pir r=14 2pi14 28pi your answer is 28 with the pi symbol on the right but I dont know how to write it on the computer was that of help?
Area of a circle = (pi)r2 [Areacircle = pi time the radius squared.] Volume of a cylinder = (pi)r2h [Volumecylinder = pi times the radius squared times the height.] (This applies to a right circular cylinder. :)
pi x r2 x h = volume of a cylinder
L × pi × r2
The height of the can in terms of Pi is: about 3.85picm
Total surface area of the cylinder in square units: (2*pi*144)+(24*pi*15) = 648*pi
2 x pi x r = A so pi=A/r times2
height = 400/pi*radius2
Volume of the cylinder: pi*radius*radius*height
Complete surface area = (2*pi*72)+(14*pi*15) = 308*pi square cm
Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches
cool
you find the answer without multiplying by pi and leave the pi sign in your answer
To be able to find the radius of the cylinder, you need to know not only its volume but also its height. The best we can do is find an expression for the radius in terms of the height of the cylinder volume of cylinder = Pi x r2 x h where r is the radius of the cylinder and h is the height of the cylinder 980 = Pi x r2 x h r = square root(980/(Pi x h))
