Draw a rectangle (your road) and divide it into seven sections. Then, shade three of the seven sections.
Answer:
8
Step-by-step explanation:
3(y - 1) + 2x²
Let x =2 and y =1
3(1-1)+2 (2)^2
3(0) +2(4)
0+8
Answer:
<em>D. Point Y is the center of the circle that passes through points </em><em>D, E, and F.</em>
Step-by-step explanation:
Circumcenter-
- The circumcenter is the center of the triangle's circumcircle and circumcircle is the circle that passes through all three of the triangle's vertices.
- Circumcenter is the point where the perpendicular bisectors of a triangle intersect.
As point Y is the circumcenter of triangle DEF, so the circle, which is the circumcircle, with centre as Y must passes through the vertices D, E, F.
Answer:
About 4.8
Step-by-step explanation:
The formula for the area is pi(r^2).
Plugging the area in to the equation, you get 72.382=pi(r^2).
Dividing both sides by pi, you get about 23.04=r^2.
Taking the square root of both sides you get about r=4.8
