| Assertion (A): If the circumference of a circle is \[\text{176 cm},\]then its radius is\[\text{28 cm}\]. |
| Reason (R): Circumference \[=2\pi \times radius\] |
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: A
Solution :
| [a] \[C=2\times \frac{22}{7}\times r=176\] |
| \[r=\frac{176\times 7}{2\times 22}=28cm\] |
