Question:
If the radius of a sphere is 2.1 cm, then the volume of sphere is equal to:
यदि एक गोले की त्रिज्या 2.1 सेमी है, तो गोले का आयतन बराबर है:
Options:
- a) 38.088 cm³
- b) 36.808 cm³
- c) 38.808 cm³
- d) 36.088 cm³
- a) 38.088 सेमी³
- b) 36.808 सेमी³
- c) 38.808 सेमी³
- d) 36.088 सेमी³
correct answer : c)
Explanation:
Volume = (4/3) * π * r^3 = (4/3) * (22/7) * (2.1)^3 = 38.808 cm³.
आयतन = (4/3) * π * r^3 = (4/3) * (22/7) * (2.1)^3 = 38.808 सेमी³।
