5. because I found it. hahaha
A nice physics problem.
But 16t 2 is inappropriately written; you meant x = 16t^2, where "^" represents exponentiation.
The appropriate formula applying to this situation includes a "t" term which is not present in yours. Start with this:
s = s_0 + v_0t + (1/2)a^t^2, where x_0 is the initial height above the ground and v_0 is the initial velocity. "a" represents acceleration an here is -32.2 ft/(sec^2).
Here's how we apply this formula:
0 ft = 64 ft + 0*t + (1/2)(-32.2 ft/(sec^2), or
0 ft = 64 ft - 16.1 ft/(sec^2)
You must solve this equation for time, t. It will be a positive quantity.

Answer:
The area of the shaded region is 7π square centimeters.
Step-by-step explanation:
Note that Circle B has a radius of 3 cm, and the two smaller circles, Circles O and C, both have a radius of 1 cm.
The area of a circle is given by:
Therefore, the area of Circle B, the entire circle, is:
The area of Circle O is:
And likewise, the area of Circle C is:
The area of the shaded area is the area of the Circle B subtracted by the area of Circles O and C. Hence:
Substitute and evaluate:
The area of the shaded region is 7π square centimeters.
