Question

What is the ratio of circumference
to area of a circle with radius 5
cm?​

Answer 1

Answer:

5:2

Step-by-step explanation:

radius of circle= 5cm

circumference= 2πr = 2π×5 = 10π

area = πr^2 = π× 5×5 = π×25 = 25π

so, ratio = 25π/10π = 5/2 = 5:2

so the ratio of circumferenceto area of a circle with radius 5 = 5:2
