How do you figure out area of a circle?
pi times radius squared. :)
How to get the area of a circle?
Figure out its radius and multiply it by pi or 3.14.
What is the relationship between the radius and the circumference?
If the figure is truly a circle, then the circumference is (Radius) x (2 pi) .
What is radius of circle with area of 4?
1.2 Area = pi X radius^2 So set Area = 4, and figure it out: 4 = pi X radius ^2 4/pi = radius^2
How do you figure out circumference and radius?
The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.
How do you figure out area of a circle?
pi times radius squared. :)
How to get the area of a circle?
Figure out its radius and multiply it by pi or 3.14.
What are three things Pi can help us figure out about a circle?
They are:- 1 Circumference of a circle = pi*diameter or 2*pi*radius 2 Area of a circle = pi*radius squared 3 2*pi*radian = a complete rotation of a circle which is 360 degrees
How do you figure the diameter of a circle?
2 times pi times radius
What is a radius square?
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
How do you figure out the diameter of a circle?
Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.
What is the relationship between the radius and the circumference?
If the figure is truly a circle, then the circumference is (Radius) x (2 pi) .
How do you figure out the radius of a circle with a circumference of 6?
r = C /2 pi
What is radius of circle with area of 4?
1.2 Area = pi X radius^2 So set Area = 4, and figure it out: 4 = pi X radius ^2 4/pi = radius^2
How do you figure out the circumference of a circle?
Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)
What is formula to figure the circumference of a circle?
Circumference = 2 x {pi} x radius = {pi} x diameter
What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
