  1. Circumference and the Cylinder

  2. You will need to know the formula: C = πD Example #1: What is the circumference of a circle whose radius is 5 m? Example #2: What is the diameter of a circle whose circumference is 21.25 cm? Round your answer to the nearest tenth.

  3. Remember the formula to find the volume of a cylinder is the area of the base times the altitude or height of the cylinder. V = πr2H Example #3 Find the volume of a cylinder with a radius of 8 cm and a height of 18 cm.

  4. Example #4: • The company will make a bolt for an airplane part in the shape of a cylinder. The diameter of the bolt needs to be 1.12 cm and the height of the bolt is 3.5 cm. • What is the volume of a single bolt? Round your answer to the nearest tenth. • If the company will make 1,296 bolts and a cubic centimeter of steel costs $.05, how much will the steel for the entire order cost?
