Lets see: diameter is the longest line across a circle (goes through the center) radius is one half the diameter Pi is the ratio of the circumference to the diameter. (3.14159 .....)


How do you get a circumference and diameter with pi?

Pi represents the ratio of the circumference of a circle to its diameter. If you know the diameter (D), then the circumference (c) is (D) *pi. If you know the circumference (C), then the diameter (D) is (C)/pi. circumference is 2PiRR is the radius.so 2R is twice the radius (a.k.a. The Diameter)That leaves you withCircumference=Diameter*PiThe circumference can be found by multiplying the diameter by pi, and the diameter can be found by dividing the circumference by pi.

How does mercury's size compare to the size of earth?

That depends what you mean by "size". Diameter: 0.38 times the diameter of Earth. Radius: same number, since the radius is half the diameter. Volume: the ratio of the diameters cubed. Mass: 0.055 times Earth's mass.


What is the difference between the area of a circle with a diameter of 8 units and the area of a circle with a radius of 2 units?

The diameter is two times the radius. a diameter of 8 units is 16 units of radius. Since area is proportional to radius squared ( pi x radius squared) then the area ratio of the bigger circl is (16/2) squared or 8 x 8 = 64 times greater.

What is th formula for the circunference of a circle?

π is the ratio between the diameter and the circumference of a circle so the formula would be : Circumference = π x Diameter or alternatively (since the radius is half the diameter) Circumference = 2π x Radius.


What is circumference in terms of pi?

As pi is the ratio of the ratio of the circumference (C) of any circle to its diameter (d), the circumference of a circle in terms of pi is: C = pi x d The circumference of a circle is pi times its diameter or 2 pi times its radius (since a diameter is 2 times the radius).


Is it possible to draw a circle whose ratio of circumference to diameter is not pi?

No, the circumference divided by the radius will always be pi for a circle.
