CBSE Class 9 Maths Surface Area Of A Cone
- The radii of two cones are equal. If their slant heights are in the ratio 5:8, find the ratio of their curved surface area.
- curved surface area of a cone is 308 cm2 and it's slant height is 14 cm find (i) radius of the base and (ii)total surface area of the cone
- If the slant height of a cone 12cm and radius of the base is 14 cm, then the total surface area is --------------.
- A conical cover is required for a chimney.It must be 24cm in diameter at the base and 16cm in height.Find the area of metal sheet required to make it.
- The slant height of a cone is increased by 10% if the radius remains the same find the increase in C.S.A
- There are two cones. The C.S.A of one is twice that of other. The slant height of latter is twice than that of former. Find radius of their height.
