to the nearest cubic yard.
The volume of a right circular cylinder can be calculated using the formula;
The diameter of the base is given to us. We divide it into two to obtain the radius.
and also the height of the cylinder is .
We substitute these values into the formula to obtain;
The total sum of money will be $320.
Let the total sum of money be represented by x.
Based on the information given, the equation to solve the question will be:
12 1/2% × x = 40
0.125x = 40
Divide by 0.125
x = 40/0.125.
x = 320
Therefore, the total sum of money will be $320.

Time taken to reach the ball to the ground is 21 seconds.
Given : A ball is launched into the sky at 272 feet per second from the roof of a skyscraper 1,344 feet tall. The equation for the ball’s height h at time t seconds is .
To find : When will the ball strike the ground?
The equation for the ball's height 'h' at time 't' is given by,
When the ball strike the ground the height of the ball became zero.
Substitute h=0 in the given equation,
Taking 16 common,
Solve by middle term split,
Reject t=-4 as time can never be negative.
Therefore, Time taken to reach the ball to the ground is 21 seconds.
