Formula for finding the circumference of cone? - Answers
WebThe length of each arc will be equal to the circumference of the cone at its base and at the height of the intersecting plane. Firstly the apex angle of the cone needs to be found from the right triangle in the diagram, ie α = tan-1 [ ½ ( C – D ) / H ]. The full slant height of the non-truncated cone can then be found from R2 = ½ C / sin α. WebThe radius of semicircle = 7 units. Using the perimeter of a semicircle formula, Perimeter of a semicircle = πr + d = πr + 2r. = (7 × 22/7 + 14) units. = (22 + 14) units. Answer: The perimeter of the semicircle is 36 units. Example 3: Using the semicircle formulas, calculate the circumference of a semi-circle whose diameter is 8 units. easy gooey butter cookie recipe
