To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³
Answer:
They are 14.2 feet high each
Step-by-step explanation:
1136/80=14.2
√64 = 8
64÷1000 = 0.0064
8÷1000=0.0008
√0.0064 = 0.0008
Answer:
$7,986.25
Step-by-step explanation:
We can use the following formula to solve:
<em>P = principal value</em>
<em>r = rate (decimal)</em>
<em>t = time (years)</em>
<em />
First, change 15% into a decimal:
15% -> -> 0.15
Since 2015 and 2020 are 5 years apart, we will use 5 for t. Now, plug the values into the equation:
Your car would be worth $7,986.25
