How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
What is the area and circumference of a circle with a diameter of 8.5MM?
Circumference: multiply the diameter by pi (approximately 3.1416). Area: Divide the diameter by 2 to get the radius. Then use the formula area = pi x r2, where r is the radius.
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
What is the circumference of the circle whose area is 16 times the area of the circle whose diameter is 1.4m?
The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
What is the diameter circumference and area of a circle with a diameter of 8?
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
What the circumference and area of a circle with diameter of eleven feet?
the circumference and area of a circle with a diameter of elleven feet are as follow. circumference:34.54 area:94.985
What is the area and circumference of a circle with diameter 55 centimeters?
what is the area and circumference of a circle with a diameter of 55 centimeters
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
What is the surface area of a sphere with a circumference of 27cm?
Circumference = 27 cm So radius, r = 27/Pi = 4.297183 cm Then surface area = 4*Pi*r2 = 232.05 cm2
What is the diameter radius circumference and area of a circle with a diameter of 6?
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
Square foot of a circle?
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
If 7 is your radius and 14 is your diameter then what is the circumference and area answer?
Circumference is about: 44 Area is about: 153.94
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
How would the area of a circumerancebe affected when the diameter of a circle is doubled or triple?
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
How is pi related to the circumference area of a circle?
Pi (approximately 3.14) is the ratio of the circumference of a circle to its diameter. It is calculated by circumference divided by diameter.
