A circle has a radius of 2. What is the ratio of its circumference to its area?
1. Find the circumference: C=πd=2πr C = 2⋅π⋅2 = 4π 2. Find the area: A = πr2 A=π⋅(22)=4π 3. Divide the circumference by the area: C A = 4π 4π = 1
1. Find the circumference:
C=πd=2πr
C = 2⋅π⋅2 = 4π
2. Find the area:
A = πr2
A=π⋅(22)=4π
3. Divide the circumference by the area:
C A = 4π 4π = 1
