Question

Suhana will draw a circle of which perimeter will be 35.2 cm. Let us see by calculating
what length of radius Suhana takes to draw a circle and what will be the area of that
circular field​

Answer 1

Answer:

Radius = 5.6 cm

Area = 98.47 cm2

Step-by-step explanation:

Perimeter = 2πr = 35.2 cm

r = 35.2/2π = 5.6 cm

Area = πr2 = π x 5.6 x 5.6 = 98.47 cm2

Answer 2

Step-by-step explanation:

$35.2 = 2\pi \: r$

$= > \frac{35.2 \times 7}{44} = r$

$= > 5.6 = r$

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

$\frac{22 \times {5.6}^{2} }{7}$

$= > 4.48$
