Find the circumference of circles with these diameters take π = 3.14
A 0.60cm b 0.7 c 4.5 d 42cm
a) The circumference of a circle with a diameter of 0.60cm can be calculated using the formula C = πd, where C is the circumference and d is the diameter.
C = 3.14 * 0.60 = 1.884 cm
b) The circumference of a circle with a diameter of 0.7cm can be calculated the same way.
C = 3.14 * 0.7 = 2.198 cm
c) The circumference of a circle with a diameter of 4.5cm can be calculated as follows:
C = 3.14 * 4.5 = 14.13 cm
d) The circumference of a circle with a diameter of 42cm can be calculated using the formula C = πd.
C = 3.14 * 42 = 131.88 cm
