Finding radius from arc

WebFind the radius, central angle and perimeter of a sector whose length of arc and area are 4.4 m and 9.24 m 2 respectively Solution : Given that l = 4.4 m and Area = 9.24 m 2. So, Area = lr/2 = 9.24 m2 (4.4 ⋅ r)/2 = 9.24 r = (2 (9.24))/4.4 r = 4.2 Hence, perimeter is l + 2r = 4.4 + 2 (4.2) = 12.8 m Now, arc length is given by (θ/360) ⋅ 2Πr = l WebRadius is the distance from the centre of the circle to its circumference.

WebOur Arc of a Circle Calculator can also help you: Find the radius of a circle, knowing only the diameter. Estimate the diameter of a circle when its radius is known. Find the length of an arc, using the chord length and arc angle. Compute the arc angle by inserting the values of the arc length and radius. Arc of a Circle Calculator. WebWe know that the central angle is 10 degrees. So you have 10 degrees over 360 degrees. So we could simplify this by multiplying both sides by 18 pi. And we get that our arc length is equal to-- well, 10/360 is the same thing as 1/36. So it's equal to 1/36 times 18 pi, so it's 18 pi over 36, which is the same thing as pi/2. east patio https://a-kpromo.com
