Question

given that measurement is in centimeters, find the circumference of the circle of the nearest tenth. (use 3.14 for pi

Answer 1

Answer: 31.4cm is the correct answer

Explanation:

31.4 cm

d = 2r = (2)(5) = 10

C = πd = 10π = 31.4

Answer 2

C = 18.8 cm

Explanation:

The diameter is 6 cm

To find the circumference, we use

C = pi*d

C = 3.14 *6

C =18.84 cm

Rounding to the nearest tenth

C = 18.8 cm
