Answer:
One-half
1
1.5
Step-by-step 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
