If you have zero dollars you can’t buy anything
Answer:
66
Step-by-step explanation:
The diameter of the circle is 21. The formula for circumference is pie*radius*2. We don't have the radius but the diameter is just double the radius so just don't multiply by 2. 21 x 22 = 462. 46s divided by 7 is 66. Enjoy your answer :D
Answer:
Step-by-step explanation:
<u>The scale factor is:</u>
Applied to the area we consider k² as the area is the product of two dimensions.
<u>Find the actual area:</u>
- 0.25 m² : (1/400)² =
- 0.25 m² * 160000 =
- 40000 m² =
- 40000 * 1/10000 hectares =
- 4 hectares
In the parallelogram ABCD, diagonals AC and BD intersect at point E.
According to the definition of parallelogram, opposite sides are equal and parallel to each other. That means, AB = DC
Now as AB and DC are parallel, so according to the property of Alternate Interior Angles, we will get:
∠EAB = ∠ECD and ∠EBA = ∠EDC
Thus , in two triangles ΔABE and ΔDCE, two angles and one side are equal. So, ΔABE and ΔDCE are congruent to each other.
That means, AE = CE and BE = DE
So, AE is congruent to CE and BE is congruent to DE
