How do you figure the diameter of a circle?
2 times pi times radius
How do you figure the area of a circle with radius of 8 cm?
A = Pi(r)2: A circle with a radius of 8 cm has an area of 201.06 square cm.
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)
How do you find the area of a shaded circle and the area of an unshaded circle on that is inside the other circle?
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
What is the area of a circle with a radius of 9.4 cm?
The formula is (pi x radius to the power of 2), so its 3.14 x 82.6= figure it out
How do you figure length of a radius?
The radius of a circle is half of its diameter
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 does a congruent figure look like?
A congruent figure is identical to another figure. Example would be like a circle with the radius of 12 meters, then the congruent figure would have to be a circle with a 12 meter radius.
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.
How do you figure the radius of a circle?
You take out your ruler and measure it.
How do you figure pi radius of a circle?
The area of any circle = pi*radius2
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.
How do you change area of a circle into radius?
Figure out the square root
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 the diameter of a circle?
2 times pi times radius
How do you figure out diameter with knowing the width?
you have to double the radius which is the distance from the center of the circle to any other point on the edge of the circle. If you mean the width is the radius then you cant figure it out. you see, the formula is 2(pi)r........r is the radius. you need to know the radius to find the diameter.
