The circumference of a pizza is 75.36 in. What is the approximate area of the circle? Answers

Mathematics

Circumference = diameter x pi

Find the diameter:

75.36 = diameter x pi

Divide both sides by pi:

Diameter = 75.36/3.14 = 24 inches.

Area = pi x r^2

R = 1/2 diameter = 12

Area = 3.14 x 12^2

Area = 452.16 in^2

The answer is D.

If a vertical line is dropped from the x-axis to the point (12, –9) in the diagram below, what is the value of sec?
dem82 [27]

Answer:

Value of \sec \theta = \frac{5}{4}

Step-by-step explanation:

Given: A vertical line is dropped from the x-axis to the point (12, -9) as shown in the diagram below;

To find the value of \sec \theta.

By definition of secants;

\sec \theta = \frac{1}{\cos \theta}

Now, first find the cosine of angle \theta

As the point (12 , -9) lies in the IV quadrant , where \cos \theta > 0

Consider a right angle triangle;

here, Adjacent side = 12 units and Opposite side = -9 units

Using Pythagoras theorem;

(Hypotenuse side)^2= (12)^2 + (-9)^2 = 144 + 81 = 225

or

Hypotenuse = \sqrt{225} =15 units

Cosine ratio is defined as in a right angle triangle, the ratio of adjacent side to hypotenuse side.

\cos \theta = \frac{Adjacent side}{Hypotenuse side}

then;

\cos \theta = \frac{12}{15} = \frac{4}{5}

and

\sec \theta = \frac{1}{\cos \theta}= \frac{1}{\frac{4}{5}} = \frac{5}{4}

therefore, the value of \sec \theta is, \frac{5}{4}
