Complete surface area = (2*pi*72)+(14*pi*15) = 308*pi square cm
height = 400/pi*radius2
1884 cm3
Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches
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))

2 (pi) (r)(h) = R= radius H= height
Volume of the cylinder: pi*radius*radius*height
height = 400/pi*radius2
Total surface area including the two end pieces = (2*pi*radius2)+(2*pi*radius*height) in square units.

The formula for surface area of a cylinder is 2*pi*r^2 + 2*pi*r*h. The radius is half of the diameter so you take your diameter, 17, and divide it by 2 to get the radius. You can plug the radius and height into the SA equation and get: 2*pi*(17/2)^2+2*pi*(17/2)*(13) which equals: 144.5pi+221pi=365.5pi
h=3r (height equals 3x's the radius) V= Pi r2h (Volume equals pi x's radius squared x's height) V= Pie r2(3r) V=Pie r3 3 V= 3Pie r3
Total surface area of the cylinder in square units: (2*pi*144)+(24*pi*15) = 648*pi
