Ronch [10]2 years ago
8 0

Answer:

28.27cm³

Step-by-step explanation:

Area of a circle:

A=\pi r^2

First, find the area of a full circle with this given radius:

\rightarrow A=(3.14159)(6)^2\\\rightarrow A=(3.14159)(36)\\\rightarrow A=113.09734\\

Now, to find the radius of a quarter circle with the same radius, just divide by 4:

\rightarrow A = \frac{113.09734}{4}\\\rightarrow A = 28.27433

The radius of the quarter circle is about 28.27cm³

Y_Kistochka [10]
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0=-(x-2)^{2}+16 \\  \\ 
(x-2)^{2}=16 \\  \\ 
x-2= \sqrt{16} \\  \\ 
x-2=4 \\  \\ 
x=6

This means the ball will hit the ground 6 seconds after Amir threw it
