Question

The difference between circumference and radius of circle is 37m. Find the circumference of the circle

Answer 1

Answer :



Given difference between Circumference and radius of circle = 37 m


Now,


As we know that


Circumference of Circle = 2πr

let radius of Circle be r



ATQ ---



$2\pi \times r \: - r \: = 37 \\ \\ we \: can \: either \: put \: the \: value \: of \: \pi \: = \frac{22}{7} \\ or \: 3.14 \\ \\ i \: am \: putting \: \pi = \frac{22}{7} \\ \\ therefore \\ \\ 2 \times \frac{22 }{7} r - r = 37 \\ \\ \frac{44}{7} r - r = 37 \\ \\ multiply \: both \: sides \: by \: 7 \\ \\ 44r -7 r = 259 \\ \\ 37r = 259 \\ \\ r = \frac{259}{37} \\ \\ r= 7$

Now r (radius) = 7m


We can find the Circumference by putting the value of radius in it, we get

Circumference =
$2 \times \frac{22}{7} \times 7 \\ \\ \frac{44}{7} \times 7 \\ \\ 44m$



Therefore Circumference = 44m

Answer 2

❤Here is your solution ❤

Circumference of the circle = 2 × π× r

Let

r = radius

Now,

Given difference of circumference and radius   = 37m

A/q

Circumference - r = 37

=>2 π r - r = 37

=>r (2π - 1 )=37

=>r (2×22/7 -1)=37

=>44/7 r -r = 37

=>37r/7= 37

=>r = 7m

Hence

circumference circle =2 π r = 2 ×22/7 × 7 = 44 m.
