a water sprinkler sends water out in in a circle .how large is the watered area if the the watering Patten is 23 ft

Dennis_Churaev [7]

I'm guessing you're saying that the sprinkler is shooting out 23 ft of water.

This would be the same as the radius of a circle, and we're trying to find the area. Use the formula.

$\sf A=\pi r^2$

Plug in what we know:

$\sf A=\pi (23^2)$

$\sf A=529\pi ft^2$

This is what they could be looking for, an exact value. If they want an approximation, we can input 3.14 for Pi:

$\sf A\approx 529(3.14)$

$\boxed{\sf A\approx 1661.06~ft^2}$

Ray BD bisects 2ABC. Use the diagram and the given angle measure to

Alenkinab [10]

Assuming you mean angle ABC and not 2ABC?
Since ray BD bisects angle ABC we can set the two angle measures given equal to each other.
2x+7=4x-41
Solve for x=24
Plug in the x to find angle ABD 2(24)+7=55
therefore angle ABD is 55 and angle DBC is 55 so angle ABC is 110

I NEED HELP ASAP!!!!!! I WILL GIVE PRAILIEST TO THE CORRECT ANSWER

Norma-Jean [14]

-13 (q + 4) = 7q + 16

I think to solve it you do this first:

-13q + -52 = 7q + 16

And then I think you do:

-6q + -36

And thats all I can remember sorry ):

Or

That -6q + -36 might be the answer I think (:

Hope I could help (:
