A diagram must be provided along with the question above. Based on my research, here is what I got.

<span>100 pi is the area of the entire circle
 That makes :
</span><span>∠ A = 45°/360 = 1/8
</span> 100pi/8 = 25 pi / 2
 
The answer is option D)25π over 2. I hope this answer helps.

Find the area of a circle with radius, <br> r<br> = 5.99m.<br> Give your answer rounded to 2 DP.
GalinKa [24]

Answer: 112.72

Step-by-step explanation: We know that the formula for area of a circle is pi*r^2. Now we plug in the values. pi*5.99^2. Next we get rid of the exponent. 5.99*5.99 = 35.8801. Now we have pi*35.8801. Now if you are gonna use actual pi for this your answer would be 112.72065857. Round it to 2 decimal points and you have 112.72 . If you do 35.8801*3.14=112.663514 -> Round this and you have 112.66. So any of them would actually work but I would stick with 112.72.

Answer this plz I dont know I think its h but IDK WHY. PLZ TELL ME THE ANSWER AND SHOW WORK PLZ. I'll give the brainliest answer
Bas_tet [7]
Your original answer is correct.If you set up a ratio table, it works. For example:
So, they amount of money she's taxed on is $55. We get this by doing 175-20.

$55 is equal to 106% because 6% is tax
Now, you want to find just 100% which is the same as no tax. To get from 106 to 11, you divide by 1.06. So, you also divide 55 by 1.06 to get $51.89
She can't go over this because she won't have enough money.

So, the answer is x≤$51.89
Hope this helps!

Sin A 4/5.<br><br> Find<br> COSA + tan A
Ivahew [28]

Answer:

Step-by-step explanation:

The opposite side (the one not connected to A) = 4

The hypotenuse is 5

The adjacent side needs to be found for the cosine and the tangent.

a^2 + b^2 = c^2

a = opposite side = 4

b = adjacent side = ?

c = hypotenuse = 5

4^2 + x^2 = 5^2

16 + x^2 = 25          

x^2 = 25 - 16

x^2 = 9

x = sqrt(9)

x = 3

cos(A) = adjacent / hypotenuse = 3/5

Tan(A) = opposite / adjacent = 4/3

cos(A) + tan(A) = 3/5 + 4/3

cos(A) + tan(A) = 9/15 + 20/15 = 29/15
