Answer:
D. 25 inch²
Step-by-step explanation:
Area of sector of a circle =(r^2∅) /2
where,
r = radius of the circle
∅= angle subtended by the arc at the center of circle in radians.
Given :
∅ =155°
radius =4.3 in
Convert 155° to radian
πradian=180°
155°=π / 180°*155°
=2.705 radians
Area of sector of a circle =(r^2∅) /2
=(4.3^2 * 2.705) / 2
=(18.49 * 2.705) / 2
=50.01545 / 2
=25.007725 inch²
Approximately 25 inch²
The linear equation is y = 0.5x
<h3>How to determine the equation?</h3>The points on the line are given as: (0,0) and (2,1)
The equation is then calculated using:
Substitute the known values
Evaluate
y = 0.5x
Hence, the equation is y = 0.5x
