Question

find the volume of a sphere of radius 11.2 CM​

Answer 1

Step-by-step explanation:

volume of the sphere=4/3πr³=4/3×22/7×11.2×11.2×11.2=5877 cm³(approx)

Answer 2

❄️ Solution :

Required volume = 4/3 πr³

= 4/3 × 22/7 × 11.2 × 11.2 × 11.2 cm³

= 5887.32 cm³

❄️ More information :

1. Surface and of a cuboid = 2 (lb + bh + hl)
2. Surface area of a cuboid = 6a²
3. Curved surface area of a cylinder = 2 πrh
4. Total surface area of a cylinder = 2 πrh(r + h)
5. Curved surface area of a cone = πrl
6. Total surface area of a right circular cone = πrl + πr³, i.e., πr (l + r)
7. Surface area of a radius r = 4 πr²
8. Curved surface area of a hemisphere = 2πr²
9. Total surface area of a hemisphere = 3πr²
10. Volume of a cuboid = l × b × h
11. Volume of a cube = a³
12. Volume of a cylinder = πr²h
13. Volume of a cone = 1/3πr²h
14. Volume of a sphere a radius r = 4/3 πr³
15. Volume of a hemisphere = 2/3πr³
