Essentially, you must multiply 22 by 400. You get 8800 km apart for your answer.

The area of sector AOB is 20.25 pi ft ^2 . Find the exact area of the shaded region.
pishuonlain [190]

Remark

If you have the area of the sector, then what you need is the area of the triangle in order to find the area of the shaded area. Just subtract the two.

Area of the triangle

The right angle makes finding the base and height very easy since they are equal

Area_Triangle = 1/2 * b * h

b = 9

h = 9

Area = 1/2 * 9 * 9

Area = 1/2 * 81

Area = 40.5

Area of the Shaded Area

Area_shaded = area of the sector - area of the triangle.

Area_shaded = 20.25 * pi - 40.5

Area_shaded = 20.25(pi - 2) <<<< Answer

Help me on this please
Rudik [331]
The paper is 16 cm by 34 cm to start with, so we started with area
.. (16 cm)*(34 cm) = 544 cm^2

A circle of diameter 16 cm has been removed. The area of that circle is
.. π*(d/2)^2 = 3.14*(16 cm/2)^2 = 200.96 cm^2

Then the area of the paper that remains is
.. 544 cm^2 -200.96 cm^2
.. = 343.04 cm^2

Can you help me with this question?
Troyanec [42]
Assuming you are focusing on the square only, then the answer is 9 inches.

You take the square root of 81 to get 9. Notice how 9^2 = 9*9 = 81. So if you're not familiar with square roots, then think backwards in a sense to get the answer.
