1. 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.
ans) 5.6m , 98.56sq.m
I need the solution.​

Answer 1

Answer:

Step-by-step explanation:

Given, the perimeter of the circle = 35.2cm

We have to find out the radius and the area of that circle

Perimeter = 2 π r, where r is the radius of the circle

⇒$r=\frac{35.2}{2\pi }$

⇒$r=\frac{35.2into7 }{2into22}$

$=\frac{246.4}{44}$

$=5.6cm$

Area = $\pi r^2$ where r is the radius of circle

$=\frac{22}{7}$×$(5.6)^2$

$=\frac{22}{7}$×$31.36=98.56cm^2$

Hope helps!!
