Question

find the diameter of a circle and its circumference if its area is 6.16 metre square​

Answer 1

Diameter= 8.8m

Circumference = 27.65m

Step-by-step explanation:

πr^2 = 6.16m^2(Area of circle)

r^2 = 6.16×22/7

r^2 = 19.36

r=4.4

Diameter = 2r = 2(4.4)=8.8m

2πr (circumference of circle)

2×22/7×4.4

27.65m
