Question

3. A wire of length 352 m is bent into the shape of a circle. Find the diameter and area of the circle.​

Answer 1

Step-by-step explanation:

diameter is 352 cm, as the whole wire is used

so

$2\pi \times radius = 352 \\ radius \: is \: 56cm$

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

$\pi \times 56 \times 56 = 9856 \: {cm}^{2}$

Answer 2

Wire will be our circumference

2πr = 352

r = 176/π

diameter = 2*176/π = 352/π

Area of circle = πr²

                    =π*176/π*176/π

                 =176*176/π

                  =9864.96 (approx)
