The measure of central angle abc is pi/2
SpletThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. SpletThe central angle of a circle is the angle based at the circle's center. In other words, the vertex of the angle must be at the center of the circle. A central angle is formed by two radii that start at the center and intersect …

Did you know?
SpletSolution: The measure of central angle ABC is π/2 radians (Given) Shaded sector = 1/4 of the area of the circle We know that Area of a circle = πr 2 = π × 6 2 = 36π So the area of ABC = 1/4 × 36π = 9π units 2 Therefore, the area of the shaded sector is 9π units 2 The measure of central angle ABC is π/2 radians. SpletThe measure of central angle ABC is π/2 radians (Given) Shaded sector = 1/4 of the area of the circle. We know that. Area of a circle = πr 2 = π × 6 2 = 36π. So the area of ABC = 1/4 …
SpletYou start from the theorem that the measure of the central angle equals the measure of the arc. Further, we note that we can also convert between degrees and radians, 360 degrees = 2π radians. So Sal sets up a simple proportion of part to whole=part to whole. In degrees, you have m
SpletAngle-based special right triangles are specified by the relationships of the angles of which the triangle is composed. The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π / 2 radians, is equal to the sum of the other two angles.. The side lengths are generally deduced from the basis of the unit circle or other geometric methods. Splet14. feb. 2024 · To find the central angle of a sector of a circle, you can invert the formula for its area: A = r² · α/2, where: r — The radius; and; α — The central angle in radians. The formula for α is then: α = 2 · A/r². To …
SpletIf you know the arc length and the radius, then the angle that is subtended by the sector is θ = L / r. where L= arc length and r = radius. (Angle in radians, of course.) Thus, the area of …
