WebJan 16, 2024 · According to mathematicians, "squaring the circle" means to construct for a given circle a square with the same area as the circle. The trick is to do so using only a compass and a straightedge. The devil is in the details: First of all we are not saying that a square of equal area does not exist. If the circle has area A, then a square with ... WebJul 9, 2024 · A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around. In that case, the sector has 1/6 the area of the whole circle. Example: Find the area of a sector of a circle if the angle ...

WebThe central angle of a circle is twice any inscribed angle subtended by the same arc. Angle inscribed in semicircle is 90°. An angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment. The opposite angles of a cyclic quadrilateral are supplementary.

Where that line intersects with the circle will be point b. The circle is defined by the equation: ( x - c.x )^2 + ( y - c.y )^2 = … WebSolution. Area of shaded region = area of outer shape – area of the unshaded inner shape. Area of a triangle = ½ bh. Area of outer shape = (½ x 15 x 10) cm 2. = 75 cm 2.. Area of unshaded inner shape = (½ x 12 x 5) cm 2. = 30 cm 2.. Area of shaded region = (75 – 30) cm 2. = 45 cm 2.. Therefore, the area of the shaded region is 45 cm 2.. Example 2 shane player insurance
