WebSo to find the area of the frustum we have: π(y + dy)(s + ds) − πys = π(yds + sdy) + πdyds But bear in mind to find the surface area, we integrate with respect to x (i.e. we have a SINGLE integral). This means that I am not … 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 …

WebSolved Examples on Surface Area of a Sphere in Terms of Diameter. Example 1: Find the surface area of a sphere with diameter = 21 units. (Use π = 22/7) Solution: Given Diameter of the sphere (D) = 21 units. Surface area of a sphere = πD 2 = (22/7) 21 2 = 22 × 3 × 21 = 1386 units 2. Answer: Surface area of the hemisphere = 1386 units 2. WebThe surface area of a sphere is defined as the region covered by the sphere’s outer surface in three-dimensional space.
