Answer:
137/(36π) ft/s
Step-by-step explanation:
The rate of change of volume will be the product of the rate of change of radius and the area of the sphere. The area of the sphere is ...
A = 4πr² = 4π(6 ft)² = 144π ft²
Then the relationship above is ...
dV/dt = A·dr/dt
548 ft³/s = (144π ft²)·dr/dt
dr/dt = (548 ft³/s)/(144π ft²) = 137/(36π) ft/s ≈ 1.2113 ft/s
Answer:
-20
Step-by-step explanation:
6(-3) - |-5| + |3|
First multiply
-18 - |-5| + |3|
Then take the absolute values
-18 - 5 + 3
Subtract
-23 +3
Add
-20
Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V =
, where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V = 
V = 28 ft³
Ais the answer I’m pretty sure
It is not.
400 decimeters = 4,000 cm
4,000 cm = 40 m
