A central angle : π / 6 = 30 °
30 ° = 360 ° / 12
The area of the sector is 1/12 of the area of a circle.
Therefore area of the sector is:
A = 36 π / 12 = 3 π
Answer: A ) 3 π in²
I THINK it may be the fourth one.
Answer:
24649-17424=7225 UNITS
Step-by-step explanation:
This step implies that Lara was using the Pythagoras theorem to find the missing length of the right triangle.
a²+b²=c², taking a and b to be the two lengths adjoined by the right angle and c the hypotenuse.
Laura's step represents the step above.
157²=24649
132²=17424
157²-132²=c²
24649-17424=7225
