The area wiped by the viper blade is approximately 486.7 square inches.
The area wiped by the wiper blade (
), in square inches, is equal to the area of the circular section described below:
(1)
Where:
- Angle, in sexagesimal degrees. 
- Inner radius, in inches.
- Outer radius, in inches.
If we know that 
, 
and 
, then the area wiped by the wiper blade is:
![A = \frac{130\pi}{360} \cdot [(25\,in)^{2}-(14\,in)^{2}]](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B130%5Cpi%7D%7B360%7D%20%5Ccdot%20%5B%2825%5C%2Cin%29%5E%7B2%7D-%2814%5C%2Cin%29%5E%7B2%7D%5D)

Answer:The center is (-5,2)
The radius is 5
Step-by-step explanation:
Equation of a circle is:
(x-h)^2+(y-k)^2=r^2
(x+5)^2+(y-2)^2=5^2
Comparing both equations we get :
The center (-5,2)
The radius is 5

Answer:

Step-by-step explanation:
2x = 10y - 8
3x + 4y + 5 = 0
2x = 10y - 8
x = 5y - 4
3x + 4y + 5 = 0
3 ( 5y - 4 ) + 4y + 5 = 0
19y - 7 = 0
19y = 7
y =
x = 5y - 4
x = 5 ( ) - 4
x =
Answer:
14/25
Step-by-step explanation:
All percentages can be represented by PERCENTAGE/100
So 56% is 56/100
Then simplify by dividing by 2
28/50 Then simplify again by 2
14/25
