The circumference also doubles.
Nothing happens. A person sitting next to you won't know that you did anything to your circle. But you'll have a bigger circle. The radius will be double the originasl radius. The circumference will be double the original circumference. The area will be four times the original area.
If the radius of a circle doubles, the circumference doubles, and so does the diameter.
4.6m. The circumference is double the radius.
the equation for the circumference is Pi * double the radius which is 3.1416 * 15.5 * 2 The circumference of a circle with a radius of 15.5cm is 97.3cm.
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 of any circle is (pi) x (diameter),and of course, the diameter is double the radius.
Double the radius.
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
Easy. First, double the radius to get the diameter. Next, multiply the diameter by pi (about 3.1416). The result is the circumference of the circle.
Double the radius and multiply by pi
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.
