Option C: is the function that represent exponential decay.
Explanation:
The exponential decay can be represented by
where
and
Option A:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option A is not the correct answer.
Option B:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option B is not the correct answer.
Option C:
From the function, we can see that and
Thus, and
Thus, the function represent exponential decay.
Hence, Option C is the correct answer.
Option D:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option D is not the correct answer.
The volume of the cylinder is the space occupied by the cylinder. The volume of the water in the cylinder is 1583.36266 in³.
<h3>What is the volume of a cylinder?</h3>The volume of the cylinder is the space occupied by the cylinder. It is calculated with the help of the formula,
As it is given that the diameter of the cylinder is 12 inches while the height of the cylinder is 15 inches, also, it has a ball of the diameter of 6 inches placed inside the cylinder, therefore, the volume of the water that is inside the cylinder is the difference in the volume of the cylinder and the volume of the spherical ball.
Substitute the values,
Now, the volume of the ball is equal to the volume of the sphere therefore, the volume of the ball can be written as,
Further, the volume of the water that is inside the cylinder can be written as,
The volume of water = Volume of the cylinder - Volume of the sphere
= 1696.46 - 113.097
= 1583.36266 in³
Hence, the volume of the water in the cylinder is 1583.36266 in³.
