A) 50
B) 94
C) 49
D) 95
Correct Answer: B
Solution :
Required perimeter = circumferences of both the circles + radii of both the circles. \[=2\left[ 2\pi r-\frac{2\pi r}{4} \right]+(7\times 4)\] \[=2\left[ \frac{6\pi r}{4} \right]+28=3\pi r+28\] where r = 7 \[=3\times \frac{22}{7}\,\times 7+28=66+28=94\]You need to login to perform this action.
