The difference between circonference &
radius of a circle is 37cm
then the
area of circle is
sol​

Answer 1

Answer:

Area of circle is 154 cm².

Explanation:

Given: Difference between circumference and radius is 37cm,

therefore, 2πr-r = 37

r(2π-1)= 37

r= 37/[(2×22/7)-1]

r=37/(44-7)/7

r= 37×7÷37

r= 7cm

Now,

area of circle= πr²= (22/7)(7)²

area of circle= 22×7= 154 cm²

this is the required answer.
