Answer 2

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.

thanks

Answer 4

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