Given:-

  • Diameter of ball = 7.0 cm means 7 cm.

⠀⠀⠀⠀⠀⠀⠀⠀

To find:-

  • Volume of ball.

⠀⠀⠀⠀⠀⠀⠀⠀

 \huge \tt \: ☃\:Solution

⠀⠀⠀⠀⠀⠀⠀⠀

We know that

✶ Volume of sphere = ⁴/₃ πr³

⠀⠀⠀⠀⠀⠀⠀⠀

In which r is Radius

⠀⠀⠀⠀⠀⠀⠀⠀

R = D/2

R = 7/2 cm

R = 3.5 cm

⠀⠀⠀⠀⠀⠀⠀⠀

Put the values

⇒ ⁴/₃ × ²²/₇ × (3.5)³

⇒ ⁴/₃ × ²²/₇ × 42.875

⇒1.333 × 3.14 × 42.875

⇒ 179.59 cm³(approx)

Therefore, Volume of ball is 179.59 cm³(approx).

More information:-

  • Ball is a type of sphere.
  • So the volume of ball and sphere will be same.
  • Volume of sphere is ⁴/₃ πr³ . In which r is Radius.
