Question

A wire of length 132cm is bent into the shape of a circle. Find the radius of the circle also find its area.( π = 22/7)
​

Answer 1

Answer:

Radius = 21 cm; Area = 1386 cm²

Step-by-step explanation:

Length of wire = Circumference of the circle = 132cm:-

$2\pi \: r = 132 = > 2 \times \frac{22}{7} \times r = 132$

$= > \frac{44r}{7} = 132$

$= > r = 132 \times \frac{7}{44} = 3 \times 7 = 21 \: cm$

$now \:area \: of \: a \: circle = \pi \: {r}^{2}$

Applying values :-

$\frac{22}{7} \times {21}^{2} = \frac{22}{7} \times 21 \times 21$

$= > 22 \times 3 \times 21 = 22 \times 63 = 1386 \: {cm}^{2}$

Radius = 21 cm; area = 1386 cm²
