To find the volume of a sphere, we can use the formula:
V = (4/3)πr³
Where V is the volume and r is the radius of the sphere.
Given that the radius r is 25 cm, we can substitute this value into the formula:
V = (4/3)π(25)³
Now, calculate 25³:
25³ = 15625
So, we update our formula:
V = (4/3)π(15625)
Next, multiply 15625 by (4/3):
V = (4 × 15625) / 3 = 62500 / 3
Now, dividing 62500 by 3 gives approximately:
V ≈ 20833.33
Finally, we can multiply this by π (approximately 3.14) to get the final volume:
V ≈ 20833.33 × 3.14 ≈ 65449.65
Thus, the volume of the sphere whose radius is 25 cm is approximately 65449.65 cm³.
