Question

if radius of hemisphere basin is 7cm , find the required area of metal sheet to manufacture 50 basins.

Answer 1

3xpiexradiusxradius=462cm^2

Answer 2

The required area of metal sheet to manufacture 50 basins is 15400 sq.cm.

Step-by-step explanation:

Radius of hemisphere = 7 cm

Curved surface area of hemisphere = $2 \pi r^2$

                                                           = $2 \times \frac{22}{7} \times (7)^2$

                                                           =$308 cm^2$

Sheet required to cover 1 basin = 308 sq.cm.

Sheet required to cover 50 basins =$308 \times 50=15400 cm^2$

Hence the required area of metal sheet to manufacture 50 basins is 15400 sq.cm.
