C) 35 cm
D) 75 cm
E) None of these
Correct Answer: A
Solution :
Explanation Option [a] is correct. According to the question \[2\pi r=4.4m\Rightarrow 2\times \frac{22}{7}\times r=4.4m\] \[\Rightarrow r=\frac{4.4\times 7}{44}=0.7m\] Hence, the radius of the circle \[r=0.7m=70cm.\]You need to login to perform this action.
