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)

Coordinate of A are (0,0)
Coordinates of A' are (5,2)
We can find the distance from A to A' using the distance formula:
Thus, rounded to nearest hundredth, AA' is equal to 5.39
Answer:
length = 20cm
breadth = 8cm
Step-by-step explanation:
solution;
length(l) = x + 12
breadth(b) = x
perimeter (p) = 56 cm
we know that,
perimeter(p) = 2(l + b)
or, 56 = 2(x + 12 + x)
or, 56 = 2(2x + 12)
or, 56 = 4x +24
or, 56 - 24 = 4x
or, 32 = 4x
or, 32 / 4 = x
x = 8
now
putting the value of x in length and breadth
length = x+ 12
=8 + 12
=20cm
breadth = 8cm
Draw a circle 5 CM find the length then divid that
Answer: the distance of the base of the house to the foot of the ladder is 6.84 feet
Step-by-step explanation:
The scenario is shown in the attached photo.
Right angle triangle ABC is formed when the ladder leans against the wall of the house.
AC = the height of the ladder
AB = x feet = distance of the base of the house to the foot of the ladder
BC is the wall of the building.
To determine x, we will apply trigonometric ratio
Cos # = adjacent/hypotenuse
Where
# = 70 degrees
Hypotenuse = 20
Adjacent = x
Cos 70 = x/20
x = 20cos70
x = 20 × 0.3420
x = 6.84 feets
