Q:
# A wheel has a radius of 10 cm. Approximately how far does it travel in 3 revolutions?A) 47.1 cm B) 94.2 cm C) 188.4 cm D) 376.8 cm

Accepted Solution

A:

188.4 c you take the radius and double it to get the diameter then you take the diameter and multiply by 3.14 to get circumference after you find the circumference you multiply by 3

so 10×2≈20 20×3.14≈62.8 62.8×3≈188.4

so 10×2≈20 20×3.14≈62.8 62.8×3≈188.4
