If you mean: (x+5)^2 +(y-8)^2 = 1
Then the centre of the circle is at: (-5, 8)
26 degrees
33
approx. 16.55 inches
circumference or perimeter of the semi-circle = (diameter*pi)/2 + diameter
Area = pi*262 = 676*pi square mm
At the center, (x, y) = (-2, 5)
There need to be squares in there for x and y - I think you're asking for the centre of the circle with equation: (x + 5)2 + (y - 3)2 = 56 in which case the centre is (-5, 3) A circle with centre (xo, yo) and radius r has equation of the form: (x - xo)2 + (y - yo)2 = r2
The circumference of a circle, C, is pi*diameter. If 52 is the diameter, then the equation becomes: C = 3.14159 * 52 or C = 163.36 inches.
It is a bit difficult to deal with this since powers are not shown clearly in the question but if the equation was: (x + 2)2 + (y - 5)2 = 25 Then the centre is (-2, 5) and the radius is 5 = sqrt(25) units.
5. A circle with centre (0,0) has equation: x2 + y2 = radius2 With: x2 + y2 = 25 = 52 The radius is 5.
Without an equality sign and not knowing the plus or minus value of 52 the given terms can't be considered to be an equation.
If you have the radius of the circle then just plug it into the equation which ispi x r2This equation is used to find the area of a circleSo if your radius is 5 then all you do is 52 and then multiply by piHope that helps.Jamz159

The equation of the circle with center (h, k) and radius r is of the form(x - h)2 + (y - k)2 = r2x2 + y2 - 10x + 6y = 47 (complete the square)[x2 - 10x + (10/2)2] + [y2 + 6y +(6/2)2] = 47 + (10/2)2 +(6/2)2(x2 - 10x + 52) + (y2 + 6y + 32) = 47 + 52 + 32(x - 5)2 + (y + 3)2 = 81(x - 5)2 + (y + 3)2 = 92So that the center of the circle is (5, -3) and the radius is 9.
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
x2 + y2 = 25 A circle with centre (xo, yo) and radius r has equation: (x - xo)2 + (y - yo)2 = r2 So with centre the origin (0, 0) and radius 5 cm, the circle has equation: (x - 0)2 + (y - 0)2 = 52 ⇒ x2 + y2 = 25
Let x be the unknown. Given: x * (1 - 0.75) = 52 Procedure: rearranging the equation, we get x = 52 / 0.25 = 208. Q.E.D. =====================
