Radius of a half circle
WebThe perimeter of a semicircle formula is defined as the sum of half of the circumference of the circle and the diameter of a circle. It is expressed as, The circumference of a circle is C = πd or C = 2πR. The perimeter of a semicircle formula = (πR + 2R) units, or R (π + 2). where, R = radius of a semicircle π (pi) is 22/7 or 3.142 approximately WebThe equation, x 2 + y 2 = 64, is a circle centered at the origin, so the standard form the parametric equations representing the curve will be x = r cos t y = r sin t 0 ≤ t ≤ 2 π, where r represents the radius of the circle. Since r 2 = 64, the value of the circle’s radius is equal to r = 8. Hence, we have the parametric equations shown below.
