The circle is centered at the origin and the length of its radius is 8 What is the circle's equation?
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
What is the center and radius of the circle with equation (x 9)2 (y 5)2 64?
If you mean: (x+9)^2 + (y+5)^2 = 64 Then the center of the circle is at (-9,-5) and the radius is 8
What is the circumference of a circle if the area is 64 pi?
Area = pi*r2 = 64*pi so that r2 = 64 or r = 8 Then circumference = 2*pi*r = 16*pi
What is the answer for the circle of 128 ft what is the radius of the circle?
If the circumference is 128 feet, the radius is 20.37 feet. If the diameter is 128 feet, the radius is 64 feet.
X2 plus y2 equals 64. what is the radius?
That's the equation of a circle with its center at the origin and a radius of 8.
What is a circunference?
the distance around a circle
How do you find the circunference of a circle?
Multiply the diameter by 'pi' .
What is the radius of 128 inch circle?
If the circle's circunference is 128 then radius is 128/2pi = about 20.372 inches
How do you determine the value of pi?
The value of pi is the relationship of a circunference to its diameter. For instance, if you have a circle whose circunference is 9.42477 cm, you shall have a diameter of 3 cm. Any measure of a circunference divided by its diameter shall generates the same numeric value, the pi number.
What is the circumference of a 64 mm diameter circle?
The circumference of the circle with a diameter of 64 mm is 64*pi = about 201 mm
What is th formula for the circunference of a circle?
π is the ratio between the diameter and the circumference of a circle so the formula would be : Circumference = π x Diameter or alternatively (since the radius is half the diameter) Circumference = 2π x Radius.
What is the word pi mean?
Pi ( π ) is the ratio of any circle' s circunference to its diameter.It's an endless number, so usually it is rounded to 3.14.So, to calculate a circunference's length, you have to do:(Diameter)x(Pi (consider it as 3.14))=(Perimeter)Here are some more digits of the Pi:3.14159265358979323846Check more about it on the realted links.
What is the area of a 64 inch circle?
That will depend on whether the 64 inches is the radius, diameter, or circumference of the circle.
What is the radius of a circle if the area is 64?
The area of a circle is (pi)(r^2). Set this equal to 64 and solve for the radius. r = sqrt(64/pi)
What is the radius of a circle with an area of 64 square feet?
Radius of circle: square root of (64/pi) = 4.5135166683 feet
If the area of a circle is 64 square units what is the diameter?
If the area of a circle is 64 square units the diameter is: 9.027 units.
