Answer:
Step-by-step explanation:
The missing figure is attached.
The volume of grain that could completely fill this silo is the sum of the volume of the cylinder and the volume of the hemisphere.
By definition, the volume of a cylinder can be calculated with this formula:
Where "r" is the radius and "h" is the height.
In this case you know that:
And the volume of a hemisphere can be found using the following formula:
Where "r" is the radius.
In this case:
Therefore, the volume of grain that could completely fill this silo, rounded to the nearest whole number, is:
Awh thank you! Hope you have a great day :)
Devin borrowed $1,058 at 13 percent for nine months.
We have to calculate the interest paid.
Interest =
Substituting the values of
Principal = $1058
Rate = 13%
Time = 9 months = year
Interest =
Interest = 103.155
= 103.16
So, Devin will pay 103.16 as the interest.
Therefore, Option A is the correct answer.
