What is a circuference?
The circumference is the perimeter of a circle
What do you call a line from the center of a circle its circuference?
Diameter deary x
How do you find the diameter if you have the radius?
The diameter is twice the radius. So multiply the radius by 2
How do you find the missing height or radius of a cone?
you find the radius of a cone by the bottom of it or the round part
How do you find the radius if the diameter is given?
the radius is half the diameter
How do you find the circumference of a circle if the radius is 1ft?
circuference is equal to the pi*r*2 if r=1ft then... Circumference is (3.14159)*(1)*(2) C=6.28318ft
What is the area of a circle that has a circuference of 35.4?
Circumference = 2*pi*Radius so radius = 5.63 units Area = pi*Radius2 = 99.7 square units.
Why is pi used?
I am 10 year old and pi is used to find the circuference of a circle. It is used because it is the ratio of the circuference to its diameter more specificly Pi is a rule in mathematics enjoy learning!!
How do you find the circumference of r equals 6?
multiply the radius (r) by 2 to get the diameter (d). so if r=6 then 2*6=12 d=12. then multiply by pi. pi=3.14. so 12 * 3.14 is 37.68 the circuference is 37.68
What is a circuference?
The circumference is the perimeter of a circle
What is circumference of a circle in terms of pi?
The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
How is pi useful?
the way to use pi is to find the circuference of a circle
What do you call a line from the center of a circle its circuference?
Diameter deary x
What is the formal definition for pi?
Pie is the ratio of circuference to the diameter of the circle
How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
How can you use radius to find the diameter?
you double the radius to find the diameter.
How do you find the radius of a circle if you know the radius?
You already know the radius.
