WebFeb 17, 2024 · The formula for finding the surface area of a cone is π r 2 + π r l. In this formula, r represents the radius of the circular base, h represents the height of the cone, l represents the slant height, and π can be approximated as 3.14. If the slant height is not given, it can be found using the formula l = r 2 + h 2. Q. WebThe formula to find the volume of a cone, whose radius is 'r' and height is 'h' is given as, Volume = (1/3) πr 2 h cubic units. Let A = Area of base of the cone and h = height of the cone. Therefore, the volume of cone= (1/3) × A × h. Since the base of the cone is circular, we substitute the area to be πr 2.
WebMar 28, 2024 · If you know a cone's height and radius, you must apply the Pythagorean theorem to find the length of the slant height of a cone. Measure the height and radius of your cone. Apply the formula: l = sqrt (r² + h²), where: l – Slant height of the cone; r – Radius of the base; and. h – Height of the cone.
