Answer:
A ≈ 2.83 units²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² ×
= π × 3² ×
=
≈ 2.83 units² ( to the nearest hundredth )
If a series of rigid transformations maps ∠E onto ∠B where ∠E is congruent to ∠B, then which of the following statements is true
?
triangles ABC and FDE, in which angles A and D are right angles
ΔABC ~ ΔFDE because of the definition of similarity in terms of similarity transformations
segment DE ~ segment AB because corresponding parts of similar triangles are proportional
ΔABC ~ ΔFDE because of the AA similarity postulate
segment DE ~ segment AB because of the definition of similarity in terms of similarity transformations
