Area = πr². So you have the diameter which is 56 millimeters. And the radius (r) is half the diameter, so the radius would be 28 mm. Square 28 would be 784, multiplied by π would equal 2463.00864mm. Rounded to the nearest hundredth would be 2843.01mm².
Answer:
280000lb
Step-by-step explanation:
In this question, we shall be calculating the amount of carbon iv oxide prevented from entering the atmosphere.
Generally we know that 1kwh produces 1.37 lbs of Carbon iv oxide in the atmosphere
Now, using a 100 watt light bulb daily for 8 hours, for a year, the amount of Carbon iv oxide produced will be;
100 * 1.37 * 8 * 365 = 40040 lb
Using a 30 watt CFL for 8hrs/ day for a year, we have;
30 * 1.37 * 8 * 365 = 120012 lb
Now calculating the amount of CO2 prevented, we have 40040 - 120012 = 280028 lb = 280000 after rounding up

I'm not sure what the answers are, but I can help. If you go to the x axis and search for 50, then go straight up to the line of best fit, you'll find the estimated height of the tree. It appears to be about 70.
Hope this helps!
