The lateral surface area of a hollow cylinder is 4224 cm2. It is cut along its height and formed a rectangular sheet of width 33 cm. Find the perimeter of the sheet.
322 cm
Length ---> x*33=4424 --> x=128 cm P=2*(128+33)= 322 cm
If a sphere is placed inside a right circular cylinder so as to touch the top, base and the lateral surface of the cylinder. If the radius of the sphere is R, then what would be the volume of the cylinder?
A cuboid with sides in the ratio of 8:5:6 is cut perpendicular its length to form three smaller cuboids of equal sides. If sum of the surface areas of all three cuboids is 1080 cm2 is more than the surface area of original cuboid, then what is the volume of original cuboid (in cm2)?
