Question

Find the cost of fencing a circular field of 560m radius at ₹332 per 10metres

Answer 1

Heya dear user !!!

Here is your answer,

================================

Given :-
radius of a circle field = 560m

We know that fencing is done on perimeter.
So,
Perimeter of the circle is also called "Circumference of the circle".

Circumference of circle = 2πr in which 'r' is the radius.

================================

Circumference of the circular field = 2πr
= 2×22/7×560

= 3520m

================================

If the cost of fencing the circular field per 10m = ₹ 332
So, = 1m = ₹332/10 = ₹33.2

Cost of fencing the circular field
= 33.2×3520
= ₹ 116864

================================

Hope it helps.
