The angle of a sector of a circle is 0.9 radians. If the radius of the circle is 4cm, find the length of the arc of the sector.
Answer Details
The formula for finding the length of an arc of a sector is given by L = rθ, where L is the length of the arc, r is the radius of the circle, and θ is the angle in radians.
Using this formula and the given values, we have:
L = 4 x 0.9
L = 3.6 cm
Therefore, the length of the arc of the sector is 3.6 cm.
Answer: 3.6 cm.
