Answer: Pi
Explanation: Pi is mathematical constant, used in maths and physics. Pi's approximate value is 3,14159. Irrational number Pi has infinitely many decimals so that's why we always say that the value is 3,14 instead of adding other decimals. It's defined as the propotion of circle's circumference to its diameter.
Answer:
D) 18.8cm²
Step-by-step explanation:
A=
r²
A=3.14x6x6
A=113.04
Since a circle has 360 degrees, 60 degrees is 1/6 of it.
1/6 of 113.04=
113.04÷6=18.84cm²
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
Answer:
2
