Question

a social welfare association supply drinking water for social affected people the drinking water is filled in water tank which is shape of cylinder with hemisphere end as shown in figure the whole lenght of tanker is 4.2m and the diameter of the base cylinder and two hemisphere are each 1.2m if they distributing drinking water to 60 people in a container each in shape of cylinder of radius 21cm and height 50cm find the quantity of water left in the container after distributing in litre​

Answer 1

Answer:

Step-by-step explanation:

L=4.2m , so it is in metre convert to cm (4.2x100=420) so, l=420

r=1.2/2=0.6) 0.6x100=60(m=cm)

Lengt of cylindr=420-(60+60)=300

total watr in a tank =volume of cylindr + v of 2(hemisher)

Pi x r2 x h +2(2/3 x pi' x r3

We get a answer

Water for 60 people = 60 x v of cylndr

R=21 h=50

wAter left in tank after distribution in litre= total water ina tank - 60( v of cylndr whose r=21 h=50)

And last convert it into litre

that is the last answer

so igave clue t0 know the answer

i hope u get it

Answer 2

Answer: WATER LEFT OUT =141.43LITRES

PLZ MARK ME AD BRAINLIEST

Step-by-step explanation:

diameter =1.2m

120cm

R=60cms

r=21cms

H=420-120=300

Volume volume of water left out is= volume of tank - 60 *Volume of Cylinder

here 60 is the tank filled by the water in the cylindrical tank so volume of the tank

Volume of Cylinder + 2 into volume of hemisphere -60 * Volume of Cylinder
