A circle has an area of 1.3 mi2. If a sector of the circle has an area of 0.7 mi2, what is the measure of the central angle in radians? 1.9 radians

0.5 radians

3.4 radians

0.1 radians

i really do not know lamo this is great

the answer is c.

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
