Given,
A cuboid is surmounted by a half-cylinder.
The base of the warehouse is 6 m x 14 m and the height is 8 meters.
To Find,
The surface area of the non-cuboidal part.
Solution,
The area of the non-cuboidal part of the warehouse will be equal to half of the Total surface area of the cylinder.
So,
Required area = 1/2*(T.S.A of the cylinder)
Required area = 1/2( 2πr (h + r) ) = πr (h + r)
Now,
Radius of cylinder = 1/2*6 = 3 m
Height of cylinder = 14 m
So,
Required area = 22/7*3(14+3) = 22/7*17*3
Required area = 160.28 m².
Hence, the area of the non-cuboidal part of the warehouse is 160.28 m².
