WebR = radius of circle (known) x = length of equilateral triangle Draw the figure (outside equilateral triangle with inscribed circle). Put a dot in the center of the circle. Draw a line from the center of the circle to a point where the circle barely touches the triangle. This forms a right angle with that line, and that length = R (radius). WebDec 14, 2024 · To find the radius of a circle with a circumference of 10 centimeters, you have to do the following: Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter, 3.18 … sohnreywarte

WebSep 15, 2024 · As with arc length, we have to make sure that the angle is measured in radians or else the answer will be way off. So converting θ = 117 ∘ to radians and using r = 3.5 in Equation 4.3.1 for the area A of the sector, we get. θ = 117 ∘ = π 180 ⋅ 117 = 2.042 rad ⇒ A = 1 2 r2 θ = 1 2 (3.5)2 (2.042) = 12.51 m2 . For a sector whose angle ... Web8 years ago. The center is at the origin. The equation of a circle in standard form is: (x−h)²+ (y−k)²=r². Where r is the radius and (h,k) is center. If either -h or -k is missing, then its value must be 0. Thus, if both are missing the circle must be … WebFeb 2, 2024 · The radius of a circle from the area: if you know the area A, the radius is r = √(A / π).
