    Case 1: Find the area, diameter and circumference of a circle with the given radius 3. Step 1: Find the area. Area = πr² = 3.14 * 3² = 3.14 * 9 = 28.26. Step 2: Find the diameter. Diameter = 2r = 2 * 3 = 6. Step 3: Find the circumference. Circumference = πd = 3.14 * 6 = 18.84. Case 2: Find the area of sector with the given radius 3 and theta 30. Step 1: Find the area. Area =πr² θ/360) = 3.14 * 3² * (30/360) = 3.14 * 9 * 0.083 = 2.35.

    Circumference is 2 times pi, and then muliply by the radius
