Answer:
t = 54 seconds
Step-by-step explanation:
The equation that models the path of a rocket into the air is given by :
It is required to find the time after which the rocket will hit the ground. When it hits the ground, the height of the rocket will becomes zero. It means,
h(t) = 0
i.e.
It means after 54 seconds, the rocket will hit the ground.
To solve this we are going to use the formula for the area of a circle: 
where
is the area of the circle
is the diameter of the circle
We know from our problem that the area of our circle is 10 inches long, so
. Lets replace that value in our formula to find :
We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.
