The area of the trapezoid is the product of the height and the average of the two bases:
<span>30 (25 + 33)/2 = 30 (58)/2 = 30 (29) = 870 square yd. </span>
<span>But we want to exclude the area of the fountain. </span>
<span>Since it's circular its area is π times the square of its radius, or 16π square yd. </span>
<span>So the area of the park, excluding the fountain, is </span>
<span>870 - 16π square yd, </span>
<span>or about 820 square yd.</span>
we conclude that the center of the circle is the point (-5, 0).
<h3>How to find the center of the circle equation?</h3>
The equation of a circle with a center (a, b) and a radius R is given by:
Here we are given the equation:
Completing squares, we get:
Now we can add and subtract 25 to get:
Comparing that with the general circle equation, we conclude that the center of the circle is the point (-5, 0).

Hello There! Shalinda's total is $29.62.
Our first step is to find 18% of $25.10. To do this, multiply 25.10 by 0.18.
25.10 x 0.18 = 4.518 (Which can be rounded up to 4.52)
So, this gives us the tip, but the question is asking what her total is, including the tip. To find her total, add the price before tip and the tip together.
25.10 + 4.52 = 29.62
So, her total with the tip is $29.62! I hope this was helpful, have a great day!
