Find the missing angle.

Answer:

C = 8.45 m

Step-by-step explanation:

The equation to find the circumference of a circle is:

[tex]C=2\pi r[/tex]

r = radius

To find the radius, divide the diameter by 2:

r = 2.69 m/2 = 1.345 m

Now, plug the radius into the equation:

[tex]C = 2\pi (1.345)[/tex]

Use a calculator to get the final answer:

C = 8.45 m

Hope this helps!!

Answer:

The formula for volume of a cone is area of a circle times height, divided by 3.

Therefore volume is pi times radius squared times height, divided by 3.

V = (3.14)(14)^2 (14)/3

V = (3.14) (196)(14)/3

V = (3.14) (2744)/3

V = 8616.16/3

V = 2872.05333

a)The high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.

b)The respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.

A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.

Modeling the depth of the Atlantic Ocean at a channel buoy off the coast of Maine is;

[tex]\rm y = 5-3 cos (\frac{\pi}{6} t)[/tex]

a) High tide's value of 'y' when the value of y is maximum. value of cosine is minimum.

The minimum value of cosθ  = 1.

The standard form to write the cos function is as;

θ=(2n+1)π

Whenever. high tides occur when it equals odd multiples of π. Similarly, at a Value of even multiples of even function, low tides are at their peak.

Hence,the high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.

At high tide;

соsӨ = - 1 (min value)

y= 5-3(-1)

y = 5+3

y=8 ft

At low tide,соsӨ = + 1 (max value)

y =5-3(1)

y= 5-3

y= 2

Hence,the respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.

Let's take this fun problem step-by-step:

Let's first analyze the triangle:  ΔBRE

  ∠B + ∠E + ∠R = 180

  45 + 35 + ∠R = 180

    ∠R = 100   ⇒ ∠BRE = 100 degrees

Now let's analyze ΔAQD

 ∠A + ∠Q + ∠D = 180

 30 + ∠Q + 50 = 180

    ∠Q = 100 degrees ⇒ ∠AQD = 180 degrees

Now let's consider another fact:

           ⇒ meaning that ∠AQD + ∠RQC = 180 degrees

              ⇒ ∠RQC = 180 degrees - ∠AQD = 180 - 100 = 80 degrees

            ⇒ meaning that ∠BRE + ∠BRC = 180 degrees

                ⇔ ∠BRC = 180 degrees - ∠BRE = 180 - 100 = 80 degrees

Now let's consider ΔQRC:

  ∠BRC + ∠RQC + ∠QCR = 180 degrees

   80 + 80 + x = 180

         x = 20 degrees

Answer: 20 degrees

Answer:

Step-by-step explanation:

The area of a 2D form is the amount of space within its perimeter. The area of the composite figure is 74.137 ft².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of the composite figure will be the sum of the area of the rectangle and the area of the semi-circle, therefore, the area of the composite figure will be,

Area = Area of rectangle + Area of the hemisphere

        = (10×6) + [(π/2)×3²]

        = 60 + 14.137

        = 74.137 ft²

Hence, the area of the composite figure is 74.137 ft².
