and 
Step-by-step explanation:
Given : A circle with the same radius as the circle shown but with a center at (-1.1).
To find : Which equation represents a circle ?
Solution :
The equation of a circle with center (h,k) and radius r is given by :

Here, we are given (h,k)=(-1,1)
and radius r=4 units
So, equation of circle will be :


or 
Therefore, the required equations of circle are
and 
Answer:
A: 360
Step-by-step explanation:
Split the trapezoid into 2 shapes
Then find the area of the rectangle on the left:
18 × 15 = 270 square yards
Now for the triangle, first find the base by subtracting the 2 parallel lines:
25 - 15 = 10 yards
0.5(10 × 18) = 90 square yards
Add both areas to find total area:
270 + 90 = 360 square yards
All this can be seen in the figure below:
Answer:
3 1/4
Step-by-step explanation:
You can do a equation:
133x=432 1/4
Which would give you 3.25 but in fraction form it is 3 1/4
Hope this helped!
Here. I drew a triangle just for this problem. :) You can find it in attachments.
To find the angle, we must use the sine function. To find the angle, we must know the sine of the angle first. The formula for the angle we are trying to find is:
(Forgot to mention,
let the angle = x)

=

Knowing this, we can now derive that:

Using our scientific calculators, we find that:

°
Which is our final answer. You may round accordingly.
Thank you, and I hope that helped. :)
