A quarter of a circle is 2/8 of a circle. Add to that an eighth (1/8) of a circle (not eight) and this equals 3/8 of a circle. This equates to 37.5 % of a circle.
The equation of the circle is: x^2 + y^2 = 81
Equation of a circle when its centre is at (0, 0): x^2 + y^2 = radius^2 Equation of a circle when its centre is at (a, b): (x-a)^2 + (y-b)^2 = radius^2
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
A unit circle is a circle of radius 1. If it's center is at the origin of an xy-coordinate system, then the equation is x (squared) + y (squared) = 1
First quarter. Second quarter. Third quarter. Fourth quarter. Circle center.
A quarter of a circle is a turn of 90 degrees'
AnswerIt's 90*A full circle is 360*, and if you divide that by 4 (quarter) you get 90 Degrees.There are 90 degrees in a quarter of a circle.
A full circle is 360o, so a quarter, (one fourth) of a circle is 90o.
Quarter circle
in a circle
A quarter of a circle is 2/8 of a circle. Add to that an eighth (1/8) of a circle (not eight) and this equals 3/8 of a circle. This equates to 37.5 % of a circle.
Circumference = (4) x (a quarter of a circle) = (pi) x (the diameter)Diameter = (4 x quarter-circle) divided by (pi)Radius = 1/2 the diameter = (2 x quarter-circle) divided by (pi)
one fourth of circle
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
A quarter of a circle is a right angle.
A quarter of a circle plus an eighth of a circle is what percent of a circle?
