You have to take the derivative of the function S(r) respect to the radius.
2, π and h are constants, so:
d [S(r)] / dr = 2πh + 4πr = 2π [h + 2r]
h = 4 , r = 4 => d [S(r) ] / dr = 2π [4 + 8] = 24π
Answer: 24π
x^4 + 7x^3 - 2x^2 - 9x - 3 - (10/x+8)
Answer:
none
Step-by-step explanation:
What the heck is that
Answer:
the sum of the two angles is 69. the angle labeled 2 is 17. all you gotta do is subtract 17 from 69, so 52 is your answer
