Radius is half of the diameter so it's 7 for the diameter.
For a
body moving with increasing acceleration, the graph will be in the form of an
exponential function. An example of the exponential function is shown in the
attached diagram.
Mathematically
exponential function can be expressed by the following equation.
<span>F(a) =
e^a, where a>0.</span>
First, we'll find the area of the large section, including the smaller section that is white.
Area of a circle: pi x r^2
A = pi x 7^2
A = 49pi x 120/360
A = 49/3 pi cm^2
Now, we'll find the area of the small section.
A = pi x 3^2
A = 9 pi x 120/360
A = 3pi cm^2
All that's left to do now is subtract.
49/3 pi - 3 pi
40/3 pi cm^2
(or 13 1/3 = 13.33 cm^2)
Hope this helps!
