Question

The radius of a circular region is 14 centimetre find the perimeter of the region region

Answer 1

Given

$\bold{Radius \ of \ the \ circular \ region} = 14 \ cm$

SOMETHING YOU NEED TO KNOW

Area of a circle = πr²

Perimeter of a circle = 2πr

Area of a semi - circle = 1/2  πr²

Perimeter of a semi - circle = πr

$\implies 2\pi r$

$\implies 2 * \dfrac{22}{7} * 14$

$\implies 2 * 22 * 2$

$\implies 88 \ cm$

$\boxed{\boxed{\bold{Therefore, \ the \ perimeter \ of \ the \ circular \ region \ is \ 88 \ cm}}}}}}$

                                                 

Answer 2

Step-by-step explanation:

Radius of the circle = 14 cm

Perimeter of circle means circumference of circle.

Circumference of circle= 2*22/7*14 =88cm.
