Question

find the amount of water displayed by a solid spherical ball of diameter 42cm​

Answer 1

Answer :

• 38808 cm³ is the amount of water displayed by a solid spherical ball

Given :

• Diameter = 42cm

To find :

• The amount of water displayed by a solid spherical ball

Solution :

Given ,

• Diameter = 42cm

First we have to find the radius

• R = D/2 = 42/2 = 21cm

The amount of water displayed by a solid spherical ball when its completely immersed in water then volume of spherical ball

As we know that,

• Volume of spherical ball = 4/3 πr³

where , r is radius (21cm)

》4/3 πr³

》4/3 × 22/7 × (21)³

》4/3 × 22/7 × (21)³

》88/21 × 21 × 21 × 21

》88 × 21 × 21

》38808 cm³

Hence , 38808 cm³ is the amount of water displayed by a solid spherical ball

Answer 2

★ Given :

• A spherical Ball whose Diameter is 42 cm

★ To find :

• Find the amount of water displayed by a solid spherical ball.

★ Solution :

• In the question it is said to find the amount of water displayed by the spherical ball.

• By using the formula of Volume of Sphere , We will get the volume of the spherical Ball

✰ Diameter = 42 cm

✰ Radius = 21 cm

Let's Find out...!

Volume of Sphere = 4/3πr³

➤ 4/3 × 22/7 × (21)³

➤ 88/21 × 21 × 21

➤ 88 × 21 × 21

➤ 38808 cm³

∴ The Amount of water is 38808 cm³
