Answer 2

Answer: ₹880

Step-by-step explanation:

Given:  Radius of Circular Garden: 10m.

Cost of fencing per meter: Rs.14.

To find: Perimeter of Circle.

Perimeter of Circle= 2πr.

= 2 x $\frac{22}{7}$ x 10 = $\frac{440}{7}$ $m^{2}$.

Now, cost of fencing.

Cost of fencing  = Perimeter*Cost per meter.

= $\frac{440}{7}$ x 14 = 440 x 2 = ₹ 880.
