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.
WebPractical applications Volume of a cone formula The formula for the volume of a cone is (height x π x (diameter / 2)2) / 3, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is (height x π x … WebOct 30, 2024 · So, to calculate the radius: Square the lateral height. Square the height. Subtract height squared from lateral height squared. Find the square root of the result from step three. The result is the radius of the cone.
WebOct 4, 2024 · The lateral surface area of the cone is equal to the area of the sector. The lateral surface area of the cone is L = π r l Since the sector has radius l, its area is A = φ 360 ∘ π l 2 where φ is measured in degrees. Since l is given, you can set L = A to solve for r. To determine the angle of inclination, solve the equation cos θ = r l for θ. Share
