Question

a cylindrical jar is full of water up to the brim,a sphere of radius 0•35 cm is immersed in the water ,how much water will flow out of the bottle​

Answer 1

Given

✭ A cylindrical jar is full of water

✭ A sphere of radius 0.35 cm is immersed in the water

To Find

◈ The water displaced?

Solution

Concept

So here we may not mind the cylinder, because here it's not needed all we habe to do is to fi d the volume of the sphere and it will be equal to the water displaced. Here we find the volume and not the area or the perimeter because the water displaced is equal to the amount of space occupied and not the area of takes

━━━━━━━━

Volume of a sphere is given by,

Volume {Sphere} = 4/3 πr³

• Radius = 0.35

Substituting the values,

➝ Volume = 4/3 πr³

➝ Volume = 4/3 × 22/7 × 0.35³

➝ Volume = 4/3 × 22/7 × 0.042875

➝ Volume = 0.18 cm³

So 0.18 cm³ of water in the cylinder will be displaced by the sphere

⪼ TSA of sphere = 4πr²

⪼ TSA of cone = πr(l+r)

⪼ TSA of cylinder = 2πr(h+r)
