WebRadius = Diameter ÷ 2. Radius Formula from Circumference. The perimeter of a circle is called its circumference. It is the boundary of a circle and can be expressed by the formula: C = 2πr. Here, C is the circumference, r is the radius of the circle, and π is the constant which is equal to 3.14159. The radius is the ratio of circumference to ... WebSep 23, 2024 · Now divide both sides by 2πr to get: (48π - 2πr 2)/2πr = h. Although this is correct, it is not simplified. This equation can be simplified before you start by dividing each expression by 2π to make it: 48π/2π = 2πrh/2π + 2πr 2 /2π. 24 = rh + r 2 then subtract r 2 from both sides to get: 24 - r 2 = rh and then divide both sides by "r ...

WebBy factoring 2πr from each term we can simplify the formula to: A = 2πr (r + h) The lateral surface area of a cylinder is simply given by: LSA = 2πr × h. Example 1: Find the surface area of a cylinder with a radius of 4 cm, and a height of 3 cm. Solution: SA = 2 × π × r2 + 2 × π × r × h. SA = 2 × 3.14 × 42 + 2 × 3.14 × 4 × 3. WebArea of sector of circle = (lr)/2 = (8 × 20)/2 = 80 square units. Example 3: Find the perimeter of the sector of a circle whose radius is 8 units and a circular arc makes an angle of 30° at the center. Use π = 3.14. Solution : Given that r = 8 units, θ = 30° = 30° × (π/180°) = π/6.
