Answer:
14.13 ft²
Step-by-step explanation:
The area of a semicircle is
We were given the radius of the semicircle to be: r=3 feet.
We were also asked to use π as 3.14.
We substitute into the formula to get:
This is the same as:
Or
The area of the semicircle is 14.13 ft²
Answer:
259200 seconds
The conversion factor from days to seconds is 86400, which means that 1 day is equal to 86400 seconds:
1 d = 86400 s
To convert 3 days into seconds we have to multiply 3 by the conversion factor in order to get the time amount from days to seconds. We can also form a simple proportion to calculate the result:
1 d → 86400 s
3 d → T(s)
Solve the above proportion to obtain the time T in seconds:
T(s) = 3 d × 86400 s
T(s) = 259200 s
The final result is:
3 d → 259200 s
We conclude that 3 days is equivalent to 259200 seconds:
3 days = 259200 seconds

<u>Answer:</u>
Option D
<u>Step-by-step explanation:</u>
In this table, the constant of proportionality, which is just the number that each <em>x</em> value is multiplied by to get the corresponding <em>y</em> value, is 7. This is because, as shown by the first row of the table, 1*7=7, and, as shown by the third row of the table, 3*7=21. Therefore, in the second row of the table, <em>y</em> should be 14, as 2*7=14, while in the fourth row of the table, <em>y</em> should be 28, as 4*7=28.
