The circumference of the tree trunk is 7.85

Mathematics

Answer:

2.5 feet

Step-by-step explanation:

Since circumference is just pi(we're using 3.14 in this case) * diameter, which is our answer, we need to divide the circumference(which is 7.58) BY 3.14, which is pi. This leaves us with the diameter, which is 2.5. The unit is already feet, so we needn't do anything about that.

Q1.
jonny [76]

Answer:

Step-by-step explanation:

You cross multiply. So it's 14 times 250 divided by 115.

That's how much you would add to the 250 mixture.

14 times 250 is 3500, Divided by 150=  23 and a third.

It does say round to the nearest gram.

So we had to add about 23 g to 250 g of flour.

The radius of a sphere is increasing at a rate of 2 mm/s. How fast is the volume increasing when the diameter is 80 mm? Evaluate
Komok [63]
Well, if it is increasing at a fixed rate of 2 mm/s, then the volume would still be increasing at a rate of 2 mm/s when the diameter is 80 mm, if I understand your question correctly.
