(a) The area is given by
... A = π·r²
The rate of change of area is the derivative of this with respect to time.
... dA/dt = π·2r·dr/dt
For the given conditions, this evaluates to
... dA/dt = π·2·(5 ft)·(3.5 ft/s) = 35π ft²/s ≈ 109.96 ft²/s
Answer:
I believe its B
Step-by-step explanation:
75%
45/60 x X/100
45x100
4500/60
What are the answers
37/6
-23/6 - 7/3
= -23/6 - 14/6 just make both have the same denominator (2x the 3 to make 6 and do same with numerator)
= 37/6 or 6 1/6
