Question

The cost of fencing a circular a field at sute of RRs 241-
per meteo is Rs. 5280 The field is to ploughed at
Ro rate of Rs.0.50 per m² . Find the cost of ploughing.
the field (Take
$\pi$
22/7)​

Answer 1

Step-by-step explanation:

cost of fencing a circular field= rs 241/m

Total cost =rs 5280

so the the circumference of circle = 5280/241

=21.90 m

so the 2πr = 21.90

2×22/7×r = 21.90

r= 21.90×7 / 2×22

r= 3.48

area of field = πr^2

22/7×3.48×3.48= 38.06m^2

cost of ploughing 1m^2 = rs. 0.50

cost of ploughing 38.06 m^2 = 38.06×0.50 = rs18.03 ans
