Solved: An arc of length pi/5 cm subtends a central angle
WebAnd it works out for every ratio. a tenth of the circumference will have a tenth of the angle. 1/pi of the circumference will have 1/pi of the angle. Now, for this, the circumference is 2pir by defenition And the angle is 2 radians. Of course the full angle all the way around is 2pi. So if we call the arc length S that gives us S/ (2pir) = 2/2pi. WebApr 16, 2024 · 3. Determine the radius of a circle whose central angle is 69.48° and the length of the arc formed is 14 cm. Solution : The central angle (69.48°) and arc length (14 cm) are already given in this problem. We must determine the radius of the circle. In this case, the central angle formula must be modified. oops something went wrong. subway
