Surface Area of Solids

Jumbo circus team is a very famous circus company in south India. They roam around in the different parts of the counts and host the circus treat for the people. When they are settling at a place, they will erect their huge circus tent for performing the show and small tents for them to stay in those days. The stage tent consists of a cylinder capped by a cone.

There is a bird bath for the birds of circus in the cylindrical shape with a hemispherical depression at one end as shown in the figure. The height of the cylinder is $1.45 \mathrm{m}$ and its radius is $30 \mathrm{cm}$. Find the total surface area of the bird-bath and use $\pi =\frac{22}{7}$.

Akhil runs a toy manufacturing company. He produces a wide variety of toys suitable for kids of different ages. One of his toys is in the shape of a cone. If the diameter of the base of the right circular cone is $21 \mathrm{m}$ and height $14 \mathrm{m}$. Find the area of the curved surface area of the cone in ${\mathrm{m}}^2$.

Akhil runs a toy manufacturing company. He produces a wide variety of toys suitable for kids of different ages. Calculate the cost required to paint a ball that is in the shape of a sphere having a radius of $14 \mathrm{cm}$. If the cost of painting the ball is $₹3.5/\mathrm{square} \mathrm{cm}$. Take $\left(\mathrm{\pi }=\frac{22}{7}\right)$
