Answer: 0.12
5^-2=0.04
the cube root of 27=3
0.04x3=0.12
the formula for the circumference of a circle is
<span>C = 2 × π × r or C = π × D </span>
<span>If either r or D is known, you can calculate the circumference by simply substituting the known value for r or D in the formula. Use 3.14 for π.
</span>RADIUS = 10DIAMETER = 20
C IS THE ANSWER
Step-by-step explanation:
The equation in the question is false.
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°.
