Formula for area of a circle with diameter
WebProblem: Find the area of a circle with a radius of 5 units. Solution: Plug in 5 for r in the formula A = πr 2 and solve. A = π5 2. A = 25π ( Follow the order of operations and square 5 before multiplying it by pi.) A = (25) (3.14) A = 78.5. Answer: The area of a circle with a radius of 5 units is 78.5 square units. WebArea of the circle, A = 300 square cm Now applying the formula, Substituting the value of are we will get, = = 19.54 cm Thus diameter value will be 19.54 cm.
