WebJan 30, 2024 · Diameter Formula of a Circle . The diameter formula is the one used to calculate the diameter of a circle. The diameter of the circle can be calculated using any of the information given below: 1. Radius of the circle 2. Circumference or perimeter of the circle 3. Area of the circle WebSolved Examples. Let us see some of the examples using Area and perimeter formulas: Example 1: Find the perimeter of a rectangular box, with length as 6 cm and breadth as 4 cm. Solution: Use the formula, Perimeter of a Rectangle = 2 (L+B) = 2 ( 6 cm + 4 cm) = 2 × 10 cm = 20 cm.
