Answer 2

Answer: The cost of fencing the rose garden is Rs. 59400

Step-by-step explanation:

Given: Radius of circle r= 63m

Now as we know circumference C of a circle is given by

$C= 2 \pi r = 2\times \dfrac{22}{7} \times 63 = 2\times 22 \times 9 =396m$

Cost of 1 m for fencing = Rs. 150

Cost of 396 m of fencing = Rs. 150 x 396 = Rs. 59400

Hence, the cost of fencing the rose garden is Rs. 59400
