Question

The area of a circle is equal to the area of a rectangle with sides 14 cm and 11cm respectively. Find the circumference of the circle.​

Answer 1

Answer:

43.97cm

Step-by-step explanation:

area of rect = l*b;

area = 14*11 = 154sq.cm

area of circle = area of rect = 154sq.cm

area of circle = 3.14*r*r

r*r = 154/3.14 = 49.04cm

r = root of 49.04 = 7.003

circumference = 2*pi*r = 2*3.14*7.003 = 43.97cm or round off - 44cm
