Answer» Given $\bold { Perimeter \ of \ a \ <klux>CIRCLE</klux>} = 154 \ m$ SOMETHING YOU NEED TO KNOW Area of a circle = πr² Circumference of a circle = 2πr $\implies <klux>2</klux>\pi r=154\\\implies r = 154/2\pi \\\implies r = \dfrac{49}{2}$ Diameter = 2(RADIUS) $\boxed{\boxed{\bold{Therefore, \ the \ diameter \ of \ the \ circle \ is \ 49 \ m}}}}$

Answer»

Given

$\bold { Perimeter \ of \ a \ <klux>CIRCLE</klux>} = 154 \ m$

SOMETHING YOU NEED TO KNOW

Area of a circle = πr²

Circumference of a circle = 2πr

$\implies <klux>2</klux>\pi r=154\\\implies r = 154/2\pi \\\implies r = \dfrac{49}{2}$

Diameter = 2(RADIUS)

$\boxed{\boxed{\bold{Therefore, \ the \ diameter \ of \ the \ circle \ is \ 49 \ m}}}}$
