Answer:
67.5 ft^2
Step-by-step explanation:
First find the area of the circle.
A = pi r^2
A = pi (8)^2
A = 64pi
There are 360 degrees in a circle
The shaded area has 121 degrees
The fraction is 121/360
The fraction shaded is 121/360
The fraction of the circle is the same as the area
121/360 A = 121/360 * 64 pi
area shaded = 67.54488889
To the nearest tenth
area shaded = 67.5
Step-by-step explanation:
400 - 100%
96 - X%
400X = 9600
X = 9600/400
X = 24%
Answer:
(0, 8 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , thus
(- 8, 0 ) → (0, 8 )
If you mean solving by rearranging the formula:
