Circumference of cone formula
WebThe surface area of a cone is the total area occupied by its surface in a 3D plane. The total surface area will be equal to the sum of its curved surface area and circular base area. Surface area of cone = πr (r+√ (h 2 +r 2 )) where r is the radius of the circular base. h is the height of cone. Or. 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.
