A car's rear windshield wiper rotates 130°. The total length of the wiper mechanism is 25 inches and the length of the wiper bla
Delicious77 [7]

The area wiped by the viper blade is approximately 486.7 square inches.

The area wiped by the wiper blade (A), in square inches, is equal to the area of the circular section described below:

A = \frac{\theta\cdot \pi}{360}\cdot (R^{2}-r^{2}) (1)

Where:

  • \theta - Angle, in sexagesimal degrees.
  • r - Inner radius, in inches.
  • R - Outer radius, in inches.

If we know that \theta = 130^{\circ}, R = 25\,in and r = 14\,in, then the area wiped by the wiper blade is:

A = \frac{130\pi}{360} \cdot [(25\,in)^{2}-(14\,in)^{2}]

A \approx 486.7\,in^{2}

The area wiped by the viper blade is approximately 486.7 square inches.

The sum of the​ length, width, and height of a rectangular package is 126 inches. If the length is 2 inches longer than five tim
taurus [48]

Answer:

Step-by-step explanation:

The length and the width are based on the height.

height: h

length: 5h + 2

width: 3h - 2

If the sum of those is 126, then:

h + 5h + 2 + 3h - 2 = 126 and

9h = 126 so

h = 14

length is 5(14) + 2 which is 72

width is 3(14) - 2 which is 40

The volume is found by multiplying the length times the width times the height:

14 * 72 * 40 = 40,320 inches cubed
