Answer:
The approximate area of the circle is <u>2462 centimeters²</u>.
Step-by-step explanation:
Given:
John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters.
Now, to get the area of the circle approximately.
Diameter of the circle = 56 centimeters.
<em>So, the radius </em><em>(r)</em><em> of the circle</em> =
Using 3.14 for π.
Now, to get the area of circle by putting formula:
<u><em>Approximately the area of the circle = 2462 centimeters².</em></u>
Therefore, the approximate area of the circle is 2462 centimeters².
We don't need to graph the line. All we have to do is use our slope formula.

Answer:
135 degrees
Step-by-step explanation:
- Angle CBD is the sum of angle ABC and angle ABD, so we find these first
- An Isosceles triangle has 2 equal sides and 2 equal angles
- Isosceles triangle theorem tells us that the 2 equal angles are respectively opposite the equal sides
- Since triangle ABC has sides AB=AC, then angle ACB = angle ABC
- So knowing that angles of triangle add up to 180, then
- Now we do the next triangle to get ABD
- Since triangle ABD has sides AB=BD, then angle BDA = angle BAD
- So knowing that angles of triangle add up to 180, then
- Now we said, angle CBD is the sum of angle ABC and angle ABD, so
