Find the volume of a cylinder made by rotating a rectangle with a width of 5 feet and a length of 8. round to the nearest whole number

The inside wheels of a car traveling on a circular path are rotating half as fast as the outside wheels. the front two wheels are six feet apart. what is the number of feet in the path traced by the inside front wheel in one trip around the circle? express your answer in the form "k \pi", where k is an integer.

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
