Question

in one corner of the drawing room a flower basket is kept inside the glass lies on the table the basket is designed in such a way that every one please to see it
the shape of flower basket is hemisphere with radius 60 cm and upper shape is
conical with height 120 cm from the bottom surface
find the CSA of hemisphere
and also find the cost of painting the glass outside is rupees 1.20 per m2 ,find the total cost of painting the CSA of the glass​

Answer 1

Answer:

find the capacity of the glass

Answer 2

Answer:

The cost of painting the CSA of glass is Rs. 8.143.

Step-by-step explanation:

We have to calculate the curved surface area of glass in which the flower basket is placed.

Glass is cylindrical,

Height of cylinder = 180cm = 1.8m

Radius of cylinder = 60cm = 0.6m

The curved surface area of the cylinder = $2\pi rh$

The curved surface area of the cylinder = $2\times \frac{22}{7} \times0.6\times1.8$

The curved surface area of the cylinder = 6.78584 $m^{2}$

Cost of painting the glass per $m^{2}$ = Rs. 1.2

Cost of painting 6.78584 $m^{2}$ = $6.78584 \times1.2$

Cost of painting 6.78584 $m^{2}$ = Rs. 8.143

Therefore, the cost of painting the CSA of glass is Rs. 8.143.
