Answer:
The volume is increasing at a rate of 33929.3 cubic millimeters per second.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere of radius r is given by:
In this question:
We have to derivate V and r implicitly in function of time, so:
The radius of a sphere is increasing at a rate of 3 mm/s.
This means that 
How fast is the volume increasing when the diameter is 60 mm?
Radius is half the diameter, so 
. We have to find 
. So
The volume is increasing at a rate of 33929.3 cubic millimeters per second.
C and D are correct because 25 > 35 so that's C.
Its also D because they are not equal.
Hope this helps :)
Answer:
A,D
Step-by-step explanation:
I KNOW BECAUSE I KNOW THAT HOW
Answer:
2 more quarts of oil is needed to fill
the engine to capacity
Step-by-step explanation:
Here, we want to calculate how many more quarts of oil is required to fill the engine to capacity
We have to convert the capacity to quarts
Mathematically, 1 gallon = 4 quarts
So 1 1/4 gallon will be 5/4 * 4 = 5 quarts
So the number of quarts needed to fill the engine to capacity will be 5 quarts - 3 quarts = 2 quarts
