What are the formulas for finding the circumference diameter and radius?
circumference: Pi(3.14) x radius squared Diameter: radius squared radius: diameter divided by 2
What is the area of a circle if the diameter is 9.75 if pi is 3.14?
The area equals pi times the radius squared. The radius is half the diameter. The area of the circle = (9.75/2)2(3.14) = 74.6240625 or about 74.6 units squared.
2 times the radius equals what?
Radius time 2 equals the diameter.
How do you find the area of a sphere?
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )
Connection between the circumference and the diameter of a circle?
Divide the diameter by 2, this will give you the radius. multiply the radius by the radius, this gives you the radius squared. Multiply the raduis squared by Pi (3.14) to get the circumference. Formula : Circumfrence = Pi X R squared so, if the diameter is 10, the radius is 5, the radius squared is 25, 25 X 3.14= circumference
What are the formulas for finding the circumference diameter and radius?
circumference: Pi(3.14) x radius squared Diameter: radius squared radius: diameter divided by 2
What are some common math formulas?
Well pythagorus theoreum is a squared plus b squared equals c squared and circumference equals pie x diameter and area equals pie x radius squared
What is Pi r squared is it the area of a circle?
Yes, it is. Hint, always remember to check that the figure given in the problem is the radius., and not the diameter. If it is the diameter, then the radius is half that.
What is the diameter of the following circle x2 plus y2 equals 144?
x2 + y2 = 144 = radius squared radius = sqrt (144) = 12 diameter = 2 x radius = 24
What is the area of a circle if the diameter is 9.75 if pi is 3.14?
The area equals pi times the radius squared. The radius is half the diameter. The area of the circle = (9.75/2)2(3.14) = 74.6240625 or about 74.6 units squared.
How do you find the radius squared?
Radius squared is half of the diameter multiplied by itself. Example: diameter is 6 inches, radius is 3 inches (half of diameter), radius squared is 9 inches (radius multiplied by itself 3 x 3 = 9).
What happens to the area of the circle when the diameter is doubled?
As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.
2 times the radius equals what?
Radius time 2 equals the diameter.
How do you find the area of a sphere?
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )

How do you calculate radius of the circle when you do not have diameter?
Double the Radius to Calculate the Diameter.
Area of a circle with 2 inch diameter?
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
