Answer:
The center of the circle is .
Step-by-step explanation:
The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:
(1)
Where:
- Center.
,
- Location of the endpoints.
If we know that and
, then the location of the center of the circle is:
The center of the circle is .
The surface area of the trapezoidal prism is: 4,190 in.².
<h3>What is the Surface Area of a Trapezoidal Prism?</h3>Surface area = (b1+b2)h + PH, where:
- Length of the base of the trapezoid (b1) = 20 in.
- Length of the base of the trapezoid (b2) = 60 in.
- Height of the trapezoid (h) = 15 in.
- Perimeter of the trapezoid (P) = 60 + 25 + 20 25 = 130 in.
- Height of the prism (H) = 23 in.
Plug in the values
Surface area = (b1+b2)h + PH = (20 + 60)15 + (130)(23)
Surface area = 4,190 in.²
