Question: 6. Pattern for a cone-shaped vent cap. Part A: The formula for the arclength L of a circle is L = = 360 * 2xr.

6. Pattern for a cone-shaped vent cap. Part A: The formula for the arclength L of a circle is L = = 360 * 2xr. Solve this formula for 0. Show your work (2 marks): Part B. (2 marks) You need to build a cone-shaped vent cap according to the following dimensions. Note there is no base to the cone because the bottom is open. Use the diagram of the cone shown on the 14.25 in left to find the circumference of the base and the slant height s. 11.75 in circumference of base = L Part C (2 marks) The pattern for the cone. Now find the angles used on the pattern to make the cone for part B. Note that the circumference of the cone base becomes L on the pattern and the slant height s is the radius r of pattern's circle. Use the formula you found in part A above to find 0 and then find o. ( is NOT 909 )
