The diameter of a car's tire is 52 cm
can someone please explain how to solve this question?
Homework Answers
0.1 km = 100 m = 10000 cm.
10000 cm / 163.4 cm/rev - 61.2 REVs.
d = 0.2 rev * 163.4 cm/rev = 32.7 cm
above ground.

QUESTION 2 A medium-growth coniferous tree planted in an urban or suburban setting after being raised in a nursery for 1 year can sequester 10.5 Kg of CO2 over a 10-year period of growth. If you lived in an average home in Australia, how many trees would you need to plant to remove the CO2 you would produce from driving your car, using electricity in your home using natural gas heating for a period of 10 years? In order to...
