A) 1.2 ˛ 1011 m B) 1.8 ˛ 1011 m C) 2.4 ˛ 1011 m D) 3.0 ˛ 1011 m, The second hand of a clock has a length of 0.30 m. What distance does the tip of the second hand … WebThe radius of the circle = 6 inches. The angle subtended by the arc = 1.5 radians. We know that the arc length is the product of the radius and the angle subtended by the arc at the center of the circle. So arc length = (6) (1.5) = 9 inches. Answer: Arc length = 9 inches.

WebSorted by: 1. Ignoring this “steering angle”, you have two relevant quantities: the distance between points, which is equal to the chord length c, and the arc length a. You're looking for a radius r and an angle θ such that. a = r θ c = 2 r sin θ 2. This results in a transcendental equation for θ: c θ = 2 a sin θ 2. WebRadians and Degrees Let us see why 1 Radian is equal to 57.2958... degrees: In a half circle there are π radians, which is also 180° π radians = 180° So 1 radian = 180°/π = 57.2958...° (approximately) To go from radians to degrees: multiply by 180, divide by π … This website pays its bills with money from advertising.
