WebJul 7, 2024 · The formula for the circumference of a circle is #2pir# so all we have to do is plug in 5 for our radius: #2pi(5)# which can be simplified to #10pi#. WebQuestion: Calculate the area of this circle, where π = 3.14. Answer: We are told that the radius of the circle is 14cm, so we can now substitute this into the formula A = π x r ²: 3.14 x 14 x 14 = 615.44 cm² Area = 615.44 cm² (units of area are always written as squares, such as cm² and m²).
