Question

The circumference of a circle is 22cm find the quadrant of a circle​

Answer 1

I get the answer of this circle's quadrant is 5.5sq m

Answer 2

$\green{circumference =2 \pi \: r }$

$2\pi \: r = 22 \\ 2 \times \frac{22}{7} \times r = 22 \\ 2 \times \frac{1}{7} \times r = 1 \\ r = \frac{7}{2}$

$\green{area \: of \: quadrant \: = \frac{1}{4} \times \pi \: r {}^{2} }$

$\frac{1}{4} \times \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \\ \frac{1}{4} \times 11 \times 7 \times \frac{7}{2}$

$\frac{539}{8} = 67.375$

$67 \: cm {}^{2} \: (approx)$
