A section of road follows a circular arc with a central angle of 23.8. The radius of the inside of the curve is 281.0 m, and the road is 15.4 m wide. What is the volume of the concrete in the road if it is 0.305 m thick?
The volume of the concrete used for the section of road is ___ m^3.
Round to five decimal places.
The area of a sector of a circle is 1/2 * r ^ 2 * theta, where r is the radius of the circle and theta is the angle.
