Answer: If the radius is 23 then the answer is 1661.9 (WHEN ROUNDED & WITHOUT). If the radius is 11.5 the answer is 415.5 (WHEN ROUNDED)
Step-by-step explanation:
The formula for the area of a circle is: radius x radius x pi/3.14
If two angles are congruent, then they are at the same degree. For example, if one angle is 20 degrees, and another is 20 degrees, then they are congruent. Hope this helps!

Applying the tangent theorem and trigonometry ratio, the measure of angle A is: 19.5°.
<h3>What is the Tangent Theorem?</h3>
The tangent theorem states that if a line is tangent to a circle, the point at which the radius is drawn to the point of tangency is a right angle.
Thus, consider triangle AKO as a right triangle.
Therefore,
- angle A = reference angle
- Ok = 5 (opposite)
- AO = 15 (hypotenuse)
Using the trigonometry ratio, SOH, we have:
sin A = opp/hyp
sin A = 5/15
sin A = 0.3333
A = 19.5°
Therefore, applying the tangent theorem and trigonometry ratio, the measure of angle A is: 19.5°.
