The equation for volume of a sphere is:

Volume = 4/3 * PI * r^3

r is the radius = 1 inch

Volume is given as 4 cubic inches per second increase.

Given: dv/dt = 4 cubic inches per second.

Need to find dr/dt

Formula for volume of a sphere is: V = 4/3 * π * r^3

so now we have:

4 in^3 = 4 * π *1^2

Divide both sides by 4 * π *1^2

4 in^3 / 4π = 1/π inch per second.

The answer is 1/π inch per second ( exact answer)

or as a decimal: 0.3183 ( round as needed).

this is a clear picture from the last one. can u show me the steps of how u worked out the answer plz
azamat

One piece at a time:

4(p+2) means 4 times everything inside the parentheses.
That's 
               4(p)  +  4(2)  =  4p + 8 .

3(2p-3) means 3 times everything inside the parentheses.
That's   
               3(2p)  +  3(-3)  =  6p - 9 .

Now add everything up:

               4p + 8 + 6p - 9 .

Add all the p's together:   4p + 6p = 10p

Add all the plain numbers together:   8 - 9 = -1

The final result is:        10p - 1 .
