Answer: I believe the volume is 4188.79 cm^3.
Step-by-step explanation: The equation for the volume of a sphere is (4/3)(pi)(r^3) = (4/3)(pi)(1000) = 4188.79 cm^3.
Answer:
D (your last option)
Step-by-step explanation:
Since the percent lost per hour is constant, this is a linear equation, and the slope-intercept form of a linear equation is:
Where <em>m</em> is the slope and <em>b</em> is the intercept.
In this case, we want to formulate how much percentage is left based on how many hours have passed, so the percent left is dependent upon the time passed. This means that the dependent quantity is the percent of battery life left, and this will be variable <em>y</em>.
Answer:
V = 432 m³
Step-by-step explanation:
The volume (V) of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A = bh ( area of triangular base, with b the base, h the perpendicular height)
Here b = 16 and h = 6 , then
A = × 16 × 6 = 8 × 6 = 48 m²
Then
V = 48 × 9 = 432 m³
