Question

The cost of fencing a circular field at the rate of 20 per metre is 4,400. The field is to be ploughed at the rate of 1.20 per sq m. Find the cost of ploughing the field.


= (0.52 0.43) x 196 = 17.64 sq cm.​

Continution....

Area of Circle

$\pi {r}^{2} \\ \frac{22}{7} \times {(35)}^{2} \\ \frac{(22 \times 35 \times 35)}{7} \\ 22 \times 35 \times 5 \\ 22 \times 175 \\ 3850$

• 3850m²

Cost of ploughing per m² = ₹1.20

Total Cost of ploughing for the circular field

$3850 \times 1.20 \\ 385 \times 12 \\ 4620$

Total Cost

• $\longmapsto\;\red{\bold{₹4620}}$

$\boxed{\sf{Area\;of\;Circle = \pi{r}^{2}}}$

$\boxed{\sf{Circumference\;of\;Circle = 2\pi{r}}}$
