Question

the circumference of a bicycle wheel is 242 cm what is the approximate length of spoke?​

Answer 1

Answer:

38.5 cm

Step-by-step explanation:

Circumference = 242 cm

Let the radius of bicycle wheel be r.

2πr = 242

r = 38.5 cm

Hence, length of spoke = 38.5 cm

Answer 2

Given

$\bold {Circumference \ of \ the \ wheel} = 242 \ cm$

SOMETHING YOU NEED TO KNOW

Area of a circle = πr²

Perimeter of a circle = 2πr

$\implies 2\pi r = 242\\\implies \pi r=121\\\implies r = 121/3.14\\\implies \underline{\underline{38.5 \ cm}}$

$\boxed{\boxed{\bold{Therefore, \ the \ approximate \ length \ of \ the \ spoke \ is \ 39 \ cm}}}$
