Question

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

Answer 1

let r is the radius =r
circumference = C
difference = 37
C-r =37
2πr-r=37
r(2π-1) =37
r(2*22/7 -1) =37
r (44-7)/7 =37
r*37/7=37
r= 37*(7/37)

r= 7m

therefore
C= 2πr

= 2*22/7*7
=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

Area of circle = π r ^2 = 3.14 × 7 × 7 = 154 sq. m.
