Assertion : If a ball is in the shape of a sphere has a surface area of 221.76cm2 , then its diameter is 8.4 cm.
Reason : If the radius of the sphere be r , then surface area, S = 4p r2 , i.e.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
DIRECTION : In the following questions, a statement of assertion (A) ...
Given, surface area of sphere = 221.76cm2
We know, surface area of sphere = 4πr2
⇒ 4(π)r2 = 221.76
⇒ r2 = 7/22​ × 221.76 × 1/4 ​= 7 × (10.08) × 1/4 ​
⇒ r = 4.2cm
Then, diameter equals 2r = 2 × 4.2 = 8.4 cm, which is true and reason is also correct.
Moreover reason is the correct explanation of assertion.
