WebJul 22, 2024 · The radius of a cone is the radius of its circular base. You can find a radius through its volume and height. Multiply the volume by 3. For example, the volume is 20. Multiplying 20 by 3 equals 60. Multiply the height by π, which is a numeric constant that begins 3. 14 and never terminates. WebIn case you want to estimate the base area (BA) then you have to provide only the radius (r): Finally in case you want to calculate the volume (V) then you have to give both the radius (r) and the height (h): Other cone formulas. Apart from the equations provided above, depending on the given variables there are few other cone formulas that may ...
WebThe surface area of a right circular cone is defined as the total region covered by the surface of the 3-D dimensional shape. It is expressed using square units, like cm 2, m 2, in 2, ft 2, etc.Let us cut and open up a right circular cone, to understand about the surface area. The curved surface forms a sector with radius 's', as shown below. WebDec 14, 2024 · You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm². Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm. Use our circumference calculator to find the radius when you only have the circumference or area of a circle.
WebStep 1: Identify the base radius of the cone and name it r. Step 2: Identify its height and name it h. Step 3: Find the lateral surface area of a cone using the formula πrL. Step 4: Represent the final answer in square units. Example: What is the lateral area of a cone having base radius = 4 units and slant height = 7 units? 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
