Question

A spherical ball is divided into two equal halves. If the curved surface area of each half is 56.57 cm?, find the volume of the spherical ball.​

Answer 1

Answer:

Volume of spherical ball = 113.04 cm³

Step-by-step explanation:

since the curved surface of half of the spherical ball = 56.57 cm²

∴ 2πr² =  56.57

⇒ r²  =  56.57 /  2 × 3.14  = 9

⇒ r = 3 cm  

Now, volume of spherical ball = 4 / 3 πr³

=  4 / 3 × 3.14  × 3  × 3  × 3  

= 113.04 cm³
