Answer:
The volume increases at a rate of 
Step-by-step explanation:
The rate of change of the radius with respect to time is 4 mm / s.
So:
Now we must find a relationship between the volume of a sphere and its radius.
The equation of the volume of a sphere is:
So:
The diameter of the sphere is 100 mm. Therefore its radius is 100/2 = 50 mm.
So:
The volume increases at a rate of :
40000 π mm ^ 3 / s = 125663.71 mm^3/s
610-187 is 423 but when you estimate it would be 400 this is your answer
I hope this helps!
The answer would be 1 1/6
just the subtract the two mixed numbers and your done
1. Yes.
cranberry juice : total cups = 1 : 5 in all cases
2. Yes.
cranberry juice : total cups = 2 : 5 in all cases
3. No.
1 : 5 is not the same as 2 : 5.
Answer:
(i)= 45 KPH, (ii) = 251 miles
Step-by-step explanation:
'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.
Then, to see how far a nine hour trip would cover, distance = speed * time = 251 miles.
