Question

the upper part of cylindrical tank is hemisphere. if height of tank is 9m circumference of base is 44m, how many litre can the tank hold?

Answer 1

Answer:

SINCE circumference of the base of the cylindrical tank is 44m.

so, C =44m

then, 2πr=44m

2×22/7×r=44

44/7r=44

so,r=44×7/44

hence r=7m

radius of the base of the cylindrical tank = radius at its top=7m

Thus, the volume of the hemispherical tank is given as,

V=2/3πr³

=2/3 ×22/7× 7³

=2/3 ×22/7 ×7×7×7

= 718.7m³( approx )

Now,

height of the hemispherical part lying above the cylindrical tank,h' =7m

Height of the cylindrical

tank +h'= 9m

so, height of the cylindrical tank = 9-h'

= 9-7= 2m

So. the volume of the cylindrical tank, v= πr²h'

v = 22/7 × 7×7×2

v= 308m³

hence ,total volume of the cylindrical tank with the hemispherical portion over it = V+v

= 718.7+308 m³

= 1026.7m³

Hence ,the given tank will hold water =

( 1026.7×1000)L=1026700L

I hope it will help you , if something is found to be a mistake so sorry for this
