<span>What is the arc length when Θ=3 pi/5 and the radius is 7 cm? </span><span>Here are the available answers...
21pi/5 cm
12pi/5 cm
6pi/5 cm
3pi/35 cm </span> Given: arc length = theta * radius arc length = (3 pi/5)(7cm) arc length = 21pi/5 cm Answer is the 1st option.
To convert a degree measure into radians, you multiply it by π/180, π = 3.14 btw, so 25 * π/180 = 25*3.14/180 = 78.5/180 = 0.43633., which is 0.44 to the nearest hundredth.
