V = πr²h
Where 'h' is the height. Using our approximation of π and the given values:
V = 3.14 x 10² x 5 = 3.14 x 100 x 5 = 1570 cubic units
Similarly, the volume of a sphere with a radius of 10 units can be calculated using the formula:
V = (4/3)πr³
Substituting the values:
V = (4/3) x 3.14 x 10³ = (4/3) x 3.14 x 1000 ≈ 4186 And it works..
