Question

Area of a circular field is 2464m. Find the circumference of
22
(Taken
7​

Answer 1

Answer:

Area of circle = 2464

$\pi {r}^{2} = 2464$

$\frac{22}{7} {r}^{2} = 2464$

${r}^{2} = \frac{2464 \times 7}{22}$

${r}^{2} = 784$

$r \: = 28$

$circumference \: = 2\pi \: r$

$= 2 \times \frac{22}{7} \times 28$

$= 2 \times 22 \times 4$

$176$

Hence , c = 176
