The shape of a gilli,in the gilli-danda game (see figure),is a combination of

The $CSA$ (Curved Surface Area) of a cylinder is equal to $\ldots \ldots \ldots$

Write 'True' or 'False' and justify your answer:
If a solid cone of base radius $r$ and height $h$ is placed over a solid cylinder having the same base radius and height as that of the cone,then the curved surface area of the shape is $\pi r \sqrt{h^{2} + r^{2}} + 2 \pi r h$.

The radius of a sphere with surface area $\frac{763}{3} \, m^{2}$ is $\ldots \ldots \ldots m$. $(\pi = 3.14)$

The slant height of a cone with radius $6 \, cm$ and height $8 \, cm$ is $\ldots \ldots \ldots \ldots cm$.

The radius of the base of a cylinder is $7 \, cm$. Then,the area of its base is $\dots \, cm^2$.
