Surface area of a flat circle
WebThe area of a rectangle is length x width. In this case, length = the height of the cylinder and width = the circumference of the end of the cylinder (the circle). The length is given, and the width can be calculated using the formula for circumference of a circle.

WebSurface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2.Visual on the figure below: A sphere's surface area can be calculated just by knowing its diameter, or radius (diameter = 2 x radius). π is, of course, the well-known … WebArea (A) A circle, geometrically, is a simple closed shape. More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. Parts of a circle
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.

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.
