WebSep 22, 2024 · In the case of a circle, the formula for area, A, is A = pi * r ^2, where r is the circle's radius. Since we know that a semicircle is half of a circle, we can simply divide that... A semicircle can be used to construct the arithmetic and geometric means of two lengths using straight-edge and compass. For a semicircle with a diameter of a + b, the length of its radius is the arithmetic mean of a and b (since the radius is half of the diameter). The geometric mean can be found by dividing the diameter into two segments …

WebThe equation of a circle centered at (a , b) with radius r is given by (x - a)^2 + (y - b)^2 = r^2 The equation of a half a circle can be deduced from the above equation by solving for y (y - b)^2 = r^2 - (x - a)^2 y - b = + - sqrt (r^2 - (x - a)^2) y = b + - sqrt (r^2 - (x - a)^2) where y = b + sqrt (r^2 - (x ... 1 Doug Dillon WebThe equation of a circle is given by (x −x1)2 +(y−y1)2 = r2 ( x − x 1) 2 + ( y − y 1) 2 = r 2. If center is at origin, then x1 x 1 = 0 and y1 y 1 = 0. Answer: The equation of the circle if its center is at origin is x2+ y2= r2. … WebThe circumference of a semicircle is half of the circle's circumference. It is defined as the measurement of the arc that forms a semicircle. It does not include the length of the diameter. ... Step 2: Once, the equation is … scorpion finder flashlight
