The answer is C.The area of the triangle in Step 3 should be doubled since there are 2 triangles.
Answer:
3 : 8
Step-by-step explanation:
The ratio of the radii is equal to the ratio of the circumference, then ratio is
12π : 32π ( divide both parts by 4π )
= 3 : 8
Answer: 149
Step-by-step explanation: <EDG = <EDF + <FDG
=86+66= 149
e know that the measure of arc in degrees is equals the measure of the central angle that intercepts the arc.
Now,the measure of arc EFG is given by Arc EFG=central angle EDG= 149
