Total surface area of the cylinder in square units: (2*pi*144)+(24*pi*15) = 648*pi
1884 cm3
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
The answer will depend on whether the larger cylinder is 4 times larger in terms of radius, cross-sectional area, or volume. If radius, multiply the smaller radius by 4. If cross-sectional area, multiply the smaller radius by 2. If volume, you do not have enough information.
height = 400/pi*radius2
2 (pi) (r)(h) = R= radius H= height
Total surface area including the two end pieces = (2*pi*radius2)+(2*pi*radius*height) in square units.
Volume of the cylinder: pi*radius*radius*height

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))
The equation for the volume of a cylinder in terms of its radius and length isV = (pi) R2 L .As we read the question, we couldn't shake the spooky feeling thatthere was supposed to be a list of choices, which we never saw.
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
