Circumference = 2 x π x radius
double radius:
new_circumference = 2 x π x (radius x 2)
= (2 x π x radius) x 2
= circumference x 2
→ if the radius is doubled, the circumference is doubled.
If the radius of a circle doubles, the circumference doubles, and so does the diameter.
The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.
The circumference also doubles.
The circumference also doubles.
It gets bigger.
It splits
The circumference is directly proportional to the radius. So increasing the radius by 50% causes the circumference to also increase by 50%.
The radius of a circle with a circumference of 110 is: 17.507
The circumference of a circle with a radius of four is: 25.13
The circumference of a circle with a radius of 6.7 is: 42.097
The circumference of a circle with a radius of 11 is: 69.12
If a circle circumference is 30 the radius is: 4.77
