The area of a circle is 28.26 square miles. What is the circle's diameter?

The diameter is 6. Explanation:

radius: 3.14r^2

28.26=3.14r^2

28.26/3.14=r^2

r^2=9

r=3

and we know that diameter is two times the radius so:

3*2=6

diameter equals 6.

if you want to check it plug back in:

3^2 * 3.14 = 28.26

hope this helped :)

What is angle B?<br><br> 1. 65°<br> 2. 55°<br> 3. 35°<br> 4. 90°
vfiekz [6]

Answer:

22°

Step-by-step explanation:

what you do is you take the angles 35° and 90°

You add them up, that would be 125°

the actual equation would be

35+90=180

 125=180

-125    

------------------

∠ B= 22°      

Hope this helps!

Reason this is wrong is i didn't notice the 10 cm

Divide $210 in the ratio 2:5
RideAnS [48]
Let us say Karen received X amount of money. Then Natasha has received (X+210).
The ratio that the money divided was 2:5.
X/(X+210) = 2/5
5X = 2(X+210)
3X = 420
X = 140
Total money shared
= X+(X+210)
= 140+140+210
= 490

So the total money shared was $490.

The bottom of a doorway to a building is 3.45 feet above the ground, and a ramp to the door for the disabled is at an angle of 6
Darya [45]

Answer:

The ramp should be 32.9 feet longer.

Step-by-step explanation:

When the ramp is at 6^{o} to the ground, its length can be determined by applying the appropriate trigonometric function. Let the length be represented by l, so that;

Sin θ = \frac{opposite}{hypotenuse}

Sin 6^{o} = \frac{3.45}{l}

l = \frac{3.45}{Sin 6^{o} }

 = \frac{3.45}{0.10453}

 = 33.0048

l = 33.0 feet

When the angle is reduced to 3^{o}, the length of the ramp would be;

Sin θ = \frac{opposite}{hypotenuse}

Sin 3^{o} = \frac{3.45}{l}

l = \frac{3.45}{Sin 3^{o} }

 = \frac{3.45}{0.05234}

= 65.9152

l = 65.9 feet

Change in length of ramp = 65.9 - 33.0

                            = 32.9

The ramp should be 32.9 feet longer.
