Question

The difference between the circumference and the radius of a circle is 37 cm. Find the area of the circle

Answer 1

Heya,

According to the question,

Difference between the circumference and the radius of a circle is 37 cm.

Therefore,
2πr - r = 37
2×3.14r - r = 37
6.28r - r = 37
5.28r = 37
r = 7

Area of circle = πr²
= 3.14×7×7
= 154 cm²

Hope this helps....:)

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.

Hope it helps you
