Answer:

One-half

1

1.5

Explanation:

Area of a circle = πr²

The circumference of a circle = 2πr

n = 3.14

r = radius

Where : = π = pi = 22/7

R = radius

when radius is 1/2

Area = π x (1/2)^2 = 0.25π

circumference = 2π (1/2) = 1

the circumference is greater than the value of the area

when radius is 1 1/2

Area = π x (1 1/2)^2 = 2.25π

circumference = 2π ( 1 1/2) = 3

the circumference is greater than the value of the area

when radius is 1

Area = π x (1 )^2 = 1π

circumference = 2π ( 1) = 2

the circumference is greater than the value of the area

when radius is 2

Area = π x (2 )^2 = 4π

circumference = 2π ( 2) = 4

circumference equals area
