Question

T = 3.14)
5. A cylindrical boiler 2 m high is 3.5 m in
diameter. It has a hemispherical lid on one
end. Find the interior volume of the boiler. answer the above question ​

Answer 1

Given:-

Diameter of cylindrical boiler = 3.5 m

So, the radius (r) = 3.5/2 = 35/20 = 7/4 m

Height (h)= 2m

Radius of hemisphere (R) = 7/4m

Total volume of the boiler

= πr²h+2/3πr³

= πr² (h+2/3r)

= 22/7×7/4×7/4 (2+2/3×7/4)

= 77/8 (2+7/6)

= 77/8×19/6

= 1463/48

= 30.48 m³
