Question

find the area and radius of a circle whose circumference is 22m

Answer 1

Answer:

According to the question,

$2\pi r = 22 \\ \implies\pi r \: = \frac{22}{2} = 11 \\ \implies\ \frac{22}{7} \times r = 11 \\ \implies \: r = \frac{11 \times 7}{22} \\ \implies \: r = \frac{7}{2} \\ \implies r = 3.5 \: m$

Area of the circle -

$\pi \times {r}^{2} \\ \implies \frac{22}{7} \times 3.5 \times3 .5 \\ \implies22 \times 0.5 \times 3.5 \\ \implies11 \times 3.5 \\ \implies38.5 \: {m}^{2}$
