Area Of A Circle Basic Math Skills Studying Math Gcse Math Remember to state the units of your answers. question 2: calculate the area of the circle below with a radius of 5 cm, giving your answers in terms of \pi. [2 marks] question 3: below is a circle with centre c and radius x\text { cm}. the area of this circle is 200\text { cm}^2. find the value of x to 1 dp. (total for question 3 is 3 marks) 3 a circle has a radius of 6.5 cm. work out the circumference of the circle. give your answer correct to 2 decimal places. Solution: step 1: write down the formula: a = πr 2. step 2: change diameter to radius: step 3: plug in the value: a = π5 2 = 25π. answer: the area of the circle is 25π ≈ 78.55 square inches. example 2: find the area the circle with a radius of 10 inches. If you are given the diameter (which is twice the radius) then you would need to divide the diameter by 2 to get the radius and the use the formula a = πr 2. example: find the area of a circle with a diameter of 8 units. use 3.14 for π. divide the diameter by 2 to get the radius. radius = 8 ÷ 2 = 4. a = πr 2 = (3.14) (4) 2 = 50.24 units 2.
