Circle arc length problems
WebSep 15, 2024 · As with arc length, we have to make sure that the angle is measured in radians or else the answer will be way off. So converting θ = 117 ∘ to radians and using r = 3.5 in Equation 4.3.1 for the area A of the sector, we get. θ = 117 ∘ = π 180 ⋅ 117 = 2.042 rad ⇒ A = 1 2 r2 θ = 1 2 (3.5)2 (2.042) = 12.51 m2 .

Find the length of the intercepted arc in cm. (Ans: 3 5π) 2) Find the area of a sector in square cm of a circle of a radius 6 cm if the central angle is 60ο. ( Ans: 6π) 3) The area of a sector of a circle with radius 6 cm is 15 square cm. Find the measure of
WebThe equation for the arc length is this: Central angle/360 = Arc length/ Circumference. Since the radius is four the circumference will be eight. The equation is 104 / 360 = s/8pi. Multiply both sides by 8 pi since we need to isolate s, and you should end up with the … Webθ1 = θ2. We will prove this theorem below. Example 1. ;If s is 4 cm, and r is 5 cm, then the number , i.e. is the radian measure of the central angle. At that central angle, the arc is four fifths of the radius. Example 2. An angle of .75 radians means that the arc is three fourths of the radius. s = .75 r. Example 3.
