I don't understand 1.
2 is ok.
3 is incorrect.
4. I don't know the shape of the diagram. If it is a square with 15 ft on a side the area is 225 and you don't need pi in the calculation. If it is a circle with the diameter of 15 ft then the area is 176.7 ft^2.
5. The conversion to grams is ok.
6. I don't see a decimal in 8583/10,000 and that in decimal form is 0.8583 which is not one of the answers.
Have I missed something?
