The difference between the circumference and radius of a circle is 37 cm. The area of the circle (π = 22/7 ) is
Answers
Step-by-step explanation:
Circumference of a circle - Radius =37cm...(Given)
We know that, Circumference of a circle =2πr (Where r = radius)
⇒2πr−r=37
⇒2×

Answer:
44cm
Step-by-step explanation:
Let r be the radius of circle.
Difference between circumference and radius of circle = 37 cm
Circumference of circle = 2\piπ r
= 2 x 22/7 x r = 44/7 x r
Now,
Difference between circumference and radius of circle = 2\piπ r - r
37 = 44/7 x r - r
37 = r(44/7-1)
37 = r(44 - 7)/7
37 = 37 / 7 x r
37 x 7/37 = r
r = 7 cm
Now , Circumference of circle = 44/7 x r
= 44/7 x 7
= 44 cm .
∴ Circumference of circle = 44 cm
