If the volume and surface area of a sphere are equal, what is its radius?
If the volume and surface area of a sphere are equal, what is its radius?
اگر کسی کرہ کا حجم اور سطح کا رقبہ برابر ہے تو اس کا رداس کیا ہے؟
Explanation
- The volume of a sphere (V) is given by V = (4/3)πr^3, and the surface area (A) is given by A = 4πr^2.
- If V = A, then: (4/3)πr^3 = 4πr^2
- Simplifying, we get: r = 3 units
