WebJul 3, 2024 · The area of a circle is the total area that is bounded by the circumference. Think of the area of the circle as if you draw the circumference and fill in the area within the circle with paint or crayons. The formulas for the area of a circle are: A = π * r^2 In this formula, "A" stands for the area, "r" represents the radius, π is pi, or 3.14. WebFeb 2, 2024 · How do I calculate the lateral surface area of a truncated cone with slant height 4? You need to know the radii to find the area. If the radii are 10 and 12, then the lateral surface area is 276.46. To derive this answer: Add together the radii: 10 + 12 = 22. Multiply the result by the slant height: 22 × 4 = 88. Multiply by π: 88π ≈ 276.46.
WebFor a right square pyramid with base side length s and slant height L, the total surface area is the area of the square base with side length s, plus the total area of four triangles each with base s and altitude L. So the total surface area is. s^2 + 4 (1/2) (sL) = s^2 + 2sL.
