Henry constructed circle A with a radius of 4 units. He then created a sector as shown in the figure below. Which of the followi
ng expressions would help him find the area of the shaded sector?
1 answer:
The picture in the attached figure
we know that
area of a sector=(∅*pi/360°)*r²--------> when ∅ is in degree
in this problem
∅=120°
r=4 units
so
area of a sector=(120°*pi/360°)*4²-------> (120°/360°)*(16*pi) units²
The <span>expressions to find the area of the shaded sector is
</span>(120°/360°)*(16*pi) units²
(1/3)*(16*pi)----> (16/3)*pi units²
the area of the shaded sector is (16/3)*pi units²

Answer:
Step-by-step explanation:
Given: In ΔGHI, =90°, IG = 6.8 feet, and HI = 2.6 feet
To find:
Solution:
Trigonometry defines relationship between the sides and angles of the triangle.
For any angle ,
= side opposite to
/side adjacent to
In ΔGHI,
Put
