How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
If he radius is 12 inches what is the diameter?
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
How do you find the the center of a circle and its radius when its equation is x squared plus y squared equals 12x -10y -12?
Remember that: (x-a)2+(y-b)2 = radius2 whereas a and b are the coordinates of the circles centre Rearrange the equation: x2-12x+y2+10y = -12 Complete the squares: (x-6)2+(y+5)2 = 36+25-12 => 49 Therefore: centre = (6, -5) and radius = 7
What is the circumference of a circle with a radius of 12?
75.398
What is the length of the tangent line from the point 9 0 to a point where it touches the circle of x2 plus 8x plus y2 -9 equals 0?
Equation of circle: x^2 +8x +y^2 -9 = 0 Completing the square: (x+4)^2 +y^2 = 25 Radius of circle: 5 Center of circle: (-4, 0) Distance from (9, 0) to (-4, 0) is 13 which is the hypotenuse of a right angle triangle Using Pythagoras' theorem: 13^2 -5^2 = 144 and its square root is 12 Therefore length of tangent line is: 12 units Note that a tangent line always meets the radius of a circle at right angles.
What is the equation of the points (-12) and has a radius of length 3?
If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
What is the equation for a circle with a center of 3.0 and a radius of 12?
(x-3)^2-(y-3)^2=(12)^2
What is the equation for a circle with a center of 3 0 and a radius of 12?
center (3,0) radius 12 So the equation is (x-3)^2 + y^2 = 144 → y^2 + x^2 - 6x - 135 = 0 in general a circle of radius r centered at (h, k) has the equation: (x - h)^2 + (y - k)^2 = r^2
What is the center and the radius of the circle x2 plus y2 equals 12x -10y -12?
Equation of circle: x^2 +y^2 = 12x-10y-12 Completing the squares: (x-6)^2 +(y+5)^2 = 49 So center of circle is at (6, -5) and its radius is 7 units
What the radius for a circle with the equation x2 plus y2 equals 12?
The radius is sqrt(12) = 3.464 (rounded)
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
If equation of a circle is x2 y2 144. What is the radius of the circle?
If you mean x^2 +y^2 = 144 then the radius of the circle is 12 units
What is the equation of a circle centered at the origin with a radius of 12?
x2 + y2 =144
If a radius of a circle is 12 meters what is its diameter?
24 meters.The diameter is twice the radius.Both radius and diameter are straight lines. The radius extends from the center of the circle to any point on the circumference. The diameter extends from any point on the circumference through the center to the circumference on the opposite side of the circle.
What is the radius of a circle with a diameter of 12?
Radius of circle: 12/2 = 6 units
What is the circumference of a circle if the radius is 12?
The circumference of a circle if the radius is 12 equals about 75.4
The diameter of a circle is 12 cm what is its radius?
If the diameter is 12 cm the radius is 6 cm.
