Answer:
-2π square inches per second
Step-by-step explanation:
The lateral surface area is the product of the height and circumference, so can be described by the formula ...
LA = 2πrh
Differentiating with respect to time, we get ...
LA' = 2π(r'h +rh')
Filling in the given values, gives ...
LA' = 2π((-0.5 in/s)(14 in) + (4 in)(1.5 in/s)) = 2π(-7 in²/s +6 in²/s)
= -2π in²/s ≈ -6.283 in²/s . . . . rate of change of lateral area
Answer:
A).300763=+ 67
b) 704969= +87
c)( - 226981)= -61
Step-by-step explanation:
The values of the cube root iyf the given numbers above will be looked up in a calculator and the estimated value will be returned back.
Going through the numbers
A).for 300763
The value of the cube root = +67
B). For 704969
The value of the cube root = +89
C). For ( - 226981)
The value of the cube root= -61
Negative x negative gives you a positive number, so just multiply the two numbers and leave your result as a positive...
-4.3 x -3.2 = 13.76
4 quarts=1 gallon
1 liter is slightly bigger than 1 quart
so
1L>1qt
times 4 both sides
4L>4qt=1gal
4L>1gal
4 liters is bigger
