Answer:
Step-by-step explanation:
<u>8 to the 3 power is</u>
The volume of the original cylinder is
... V = π·r²·h
For r=1 and h=1, this is
... V = π·1²·1 = π
For the new cylinder, the volume is 1.089 times that amount.
... V = 1.089π = π·1.1²·(1-k)
... 1.089/1.21 = 1-k
... k = 1 - 1.089/1.21 = 1 - 0.9 = 0.1 = 10%
The appropriate choice is (B) 10.
It's true, just draw the sides and you'll see there's no other angle you could get.
Answer:
V = 929.7
Step-by-step explanation:
Given the equation:
= 
The integral of the above equation is:
= 
Re-organizing the integrals:
= 
Integrating:
ln(CA) - ln(CA0) = 
Inputting the initial conditions of CA and the values of k and V0:
ln(7) - ln(100) = 
1.946 - 4.605 = -0.00286V
-2.659 = -0.00286V
=> V = 
V = 929.720
Approximating to one decimal place,
V = 929.7
Answer:
About 1,237 cubic feet.
Step-by-step explanation:
The first step is to know the formula for the volume of a cylinder.
V = pi * r^2*h
You have all the numbers needed because 7ft is the height and the half the diameter (or half of 15) is 7.5. so:
V = pi * 7.5^2 * 7
