Step-by-step explanation:
Step-by-step explanation:
Area of Sector
= θ/360° * πr² (degrees) or 0.5r²θ (radians)
Question 11:
- (88°)/360° * π(19)² = 277.23ft².
Question 12:
- (260°)/360° * π(11)² = 274.54mi².
Question 13:
- 0.5(6.2)²(7π/12) = 35.22km².
Question 14:
- 0.5(7.1)²(5π/3) = 131.97cm².
Question 15:
- (215°)/360° * π(4.5)² = 37.99yd².
Question 16:
- 0.5(21.4)²(13π/18) = 519.54m².
Answer:
Yes! The given quadrilateral represents Parallelogram.
Reason: The given quadrilateral has opposite sides congruent.
Step-by-step explanation:
Given the quadrilateral with the four vertices.
- Now in order to determine whether the given quadrilateral is a parallelogram or not, we need to check whether the opposite sides are congruent or not.
- It is clear that the given quadrilateral has opposite sides congruent.
Therefore, the given quadrilateral represents Parallelogram.
Hence,
Yes! The given quadrilateral represents Parallelogram.
Reason: The given quadrilateral has opposite sides congruent.
