hala mate,
Given,
Radius of the hemispherical basin = 14cm
To find out,
Find the area of steel sheet required to manufacture the 1000 hemispherical basins.
Solution:
Surface area of a hemispherical basin = 2πr^2 = 2 × 22/7 ×14 ×14 = 1232
Therefore the area of the steel sheet required for one basin is 1232cm^2.
Total area of sheet required for 1000 hemispherical
basins = 1232 X 1000
= 1232000 cm^2
= 123.2 m^2
Therefore the area of steel sheet required to manufacture the 1000 hemispherical basins is 123.2 square meters.
hope it helps...
