The area of the sector of a circle with radius 3 yards formed by a central angle of 2.1 radians is square yards.

A circle has a radius of 27 inches. Find the length of the arc intercepted by a central angle of160 .

The central angle corresponding to a circular brake shoe measures 60. To two decimal places how long is the curved surface of the brake shoe if the length of the radius is 7 in.

When radii OA and OB are placed so that they coincide, a 240 sector of a circle is sealed to form a right circular cone. If the length of the radius of the circle is 6.4 cm, what is the lateral area of the cone that is formed? Use a calculator and round the answer to the nearest tenth of a square inch.
