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 area quadruples.
The circumference also doubles.
It splits
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.
It quadruples.
The area quadruples.
the area of the circle is increased by 400%
since C=2Pixr, if we double r, we need to double C also. 2C=2Pix 2r
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%.
