Answer:
Find answers below.
Step-by-step explanation:
The question isn't so complete but I would have to improvise so as to assist you.
Therefore, let's assume the values given are diameters of the circle.
However, if it's the radius, you'll just have to use the formula 2πr.
Given the following data;
Pie, π = 3.14
1. Diameter = 15 cm
Mathematically, the circumference of a circle (C) with diameter (D) = πD
C = 3.14 * 15
C = 47.1 cm
2. Diameter = 34 inches
C = 3.14 * 34
C = 106.76 inches
3. Diameter = 300 mm
C = 3.14 * 300
C = 942 mm
4. Diameter = 20 cm
C = 3.14 * 20
C = 62.8 cm
5. Diameter = 62 cm
C = 3.14 * 62
C = 194.68 cm
