Chapter C, Problem 8E
To determine

To find: The radius of the circular sector with angle 3π4.

Expert Solution

Answer to Problem 8E

The radius of a circular sector with angle 3π4 is 8π cm.

Explanation of Solution

The length of the circular disc is a=rθ where the radius r and θ is the central angle.

Here, it is given that a=6 cm and θ=3π4.

Substitute the value a=1 m and r=1.5 m in the formula a=rθ.

r=aθ=6(3π4)=243π=8π

Thus, the radius of the circular sector is 8π cm.
