The answer is C that can be the x-intercepts of the parabola
20 aahahahahahahHHajajajahaj ajajaja
The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.
Answer:
C = 56.52 inches
Step-by-step explanation:
Given the following data;
Diameter, D = 18 inches
Pie, π = 3.14
To find the circumference of the circle;
Mathematically, the circumference of a circle is given by the formula;
Circumference of circle, C = πD
Where, D is the diameter of a circle.
Substituting into the formula, we have;
C = 3.14 * 18
C = 56.52 inches
