Volume = pi*22*5 cubic cm
The formula for the volume of a cylinder is Pi x r^2 x height. So this cylinder's volume is Pi (2cm)^2 x 5cm = 62.83 cubic cm
Base area = pi*r2 = 78.5 sq cm
The volume is 141.37 cubic meters.
Designate the radius by r and the height by h. For any cylinder, volume = 2 X pi X r X h. From the problem statement, h = 7/5 r. Substituting this into the general volume equation yields 2 X pi X r X (7/5)r = volume (stated to be 550 cm3). Multiplying by 5 and collecting like terms yields 2 X pi X 7 r2 = 2750; r2 = 2750/[(2)(pi)(7)] = about 62.526; r = about 7. 9 cm.
