Answer:
r=d/2=18/2=9cm
circumference=2πr=2×3.14×9=56.52cm
Answer:
when in doubt, the answer is 0
Step-by-step explanation:
These triangles can be proven congruent by using ASA RULE.
What is congruent triangles and its rules ?
When two triangles are congruent, their three sides and their three angles match precisely.
If there is a turn or a flip, the equal sides and angles might not be in the same place, but they are still present.
ASA rule stands for Angle-Side-Angle rule which means two angles and a side of both triangles are equal.
Main Body:
In ΔTUV and ΔTWV
VT =VT ----(1)
∠VTU=∠TVW -----(2)
As TUVW is a parallelogram
so, ∠T = ∠U
hence, ∠TVU =∠VTW ----(3)
taking equation 1, 2,3
therefore, ΔTUV ≅ ΔTWV by ASA rule which means by Angle- Side- Angle rule.

77 times 100 is 7,700. So your answer is 7,700
Total number of marbles : 12
amount of blue marbles : 4
4/12 = 1/3 or 33%
the probability of choosing a blue marble 1/3 or 33%
