Answer:

∠ C ≈ 66.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanC = \frac{opposite}{adjacent} = \frac{DE}{CE} = \frac{7}{3} , then

∠ C = tan^{-1} ( \frac{7}{3} ) ≈ 66.8° ( to the nearest tenth )

AnnZ [28]

Answer:

9\frac{7}{8}

Step-by-step explanation:

6\frac{3}{4} + 3\frac{1}{8}, You have to make it so they have a common denominator

6\frac{6}{8}+ 3\frac{1}{8}

This would make the answer

9\frac{7}{8}

A circle has an area of 36 m2. What is the area of a 40 sector of this circle?
ruslelena [56]
The ratio of the area of the sector (S) to the area of the entire circle (C) is equal to the ratio of the angle subtended to form the sector (As) to the angle for the whole revolution (Ac)
                                  S / C = As / Ac
Substituting the given,
                                  S / 36 m² = 40 degrees / 360 degrees  
Solving for S gives, S = 4. Thus, the area of the sector is 4 m².

How do u guys solved this?
TEA [102]

Answer:

3 boxes

Step-by-step explanation:

First, we need to find the area of the whole square, so we can find out how much to subtract from. We can easily do this by multiplying 16 by 16, since it is a square.

16*16=256 square feet.

Now, we just need to find the area of the circular rug, and subtract it from 256 to find the area not covered by the rug that needs to be tiled. Since the sides of the rug touch each side of the floor, than the diameter will be the same as the side length of the square. Thus, the diameter is 16.

Now we can use the equation <em>A=pir^2 </em>or <em>Area=pi*radius squared</em> to find the area of the circle. The radius is halve of the diameter, so divide 16 by 2 to get the radius, or 8. Now all we have to do is square 8 and multiply it by 3.14.

8^2=64

Now multiply.

64*3.14=200.96.

The area of the circle is 200.96, so subtract 200.96 from 256.

256-200.96=55.04.

So they will need 3 boxes to cover the area left.

Hope this helps!

What is the area of a circle with a diameter of 8 meters? Use 3.14 for pi, nothing else. Express in pi term and number term.
juin [17]

The two answers you are looking for are 16π m² and 50.24 m².

Solution:

Finding the area of the circle,

First, knowing what the area of a circle formula is:

A=πr²

Since knowing that the radius is half the length of the diameter,

If the diameter is 8, then the radius must be 4.

A=π(4)²

A=16π m²

Now, you have the first answer. If you want to express it differently,

Using 3.14 as pi,

So, therefore,

A=16(3.14)

A=50.24 m²

So, now, we can conclude that the two answers you are looking for for the area of this circle are 16π m² and/or 50.24 m².
