WebThe 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 … WebThus, the length of the arc ABwill be 5/18 of the circumference of the circle, which equals 2πr, according to the formula for circumference. length of arc AB= (5/18)(2πr) = (5/18)(2π(18)) = 10π. Thus, the length of arc ABis 10π. The total length of the perimeter is thus 36 + 10π. The answer is 36 + 10π. Report an Error
WebIf the angle is equal to 360 degrees or 2π , then the arc length will be equal to circumference. Furthermore, the proportion between angle and arc length remains constant, so the arc length equation will be: • L / θ = C / 2π. • In the formula for arc length the circumference C = 2πr. • L / θ = 2πr / 2π. • After division there ...
