The only circular part in a cylinder is its base.
True
False
A cylinder consists of 2 circular parts – one at the top and other at the bottom.
Hence, the statement is false.
The radii of the internal and external surfaces of a metallic spherical shell are 3 cm and 5 cm respectively. It is melted and recast into a solid right circular cylinder of height 1023 cm. Then, the diameter of the base of the cylinder = 7 cm.
The total surface area of a right circular cylinder of height 13m and radius 7m is 572 sq. meter. State whether the given statement is true or false. (Take pi=227)
