The difference between the circumference and radius of a circle is 37c

1.	The difference between the circumference and radius of a circle is 37cm. Using π = 22/7, find the circumference of the circle.
Answer» Circumference of a circle – Radius = 37 cm (given) We know that, Circumference of a circle = 2πr (where r = radius) 2πr – r = 37 2 x 22/7 x r – r = 37 (37/7)r = 37 r = 7 cm Therefore, circumference of a circle = 2πr = 2 x 22/7 x 7 = 44 cm

Answer»

Circumference of a circle – Radius = 37 cm (given)

We know that, Circumference of a circle = 2πr (where r = radius)

2πr – r = 37

2 x 22/7 x r – r = 37

(37/7)r = 37

r = 7 cm

Therefore, circumference of a circle = 2πr = 2 x 22/7 x 7 = 44 cm
