The tangent line is perpendicular to the radius from the center of the circle to the point of tangency.
ΔDCE is similar to ΔDBA
DC/DB=DE/DA
15/50=DE/40
DE=12
The area of the figure is 28 yd^2
I cant see the triangle so its kinda hard to know
Answer:
The radius is 4 feet
Step-by-step explanation:
<u>Area of a circle: A = π * r^2</u>
<u />
<u>Step 1: Solve for r</u>
16π / π = π * r^2 / π
sqrt(16) = sqrt(r^2)
<em>4 = r</em>
