Question

Formula radius of circle when the circumference given

Answer 1

hello my friend !

let's derive the formula

we know circumference c=2πr
clearly r=c/2π

or we also know π = circumference / diameter
π = c/2r

2r =c/π

r= c/2π again

mark as brainiest if helped

Answer 2

Hey mate!

Here's your answer!!

We know that,

There are 2 ways to calculate circumference of a circle

Circumference of a circle = 2 x π x radius

Circumference of a circle = π x Diameter

Since you want to find the radius with circumference given,

$radius \: = \frac{c}{2\pi}$
Hope it helps you!
