Answer:

  cone: 138.16 in²

  pyramid: 352 m²

Step-by-step explanation:

Use the appropriate formula from your list of area and volume formulas.

<u>Area of a Cone</u>

  A = πr(r +h) . . . . . where r is the radius and h is the slant height

The radius is half the diameter, so is 4 inches.

  A = π(4 in)(4 in + 7 in) = 44π in² ≈ 138.16 in²

__

<u>Lateral Area of a Square Pyramid</u>

  A = 2sh . . . . . where s is the side length of the base and h is the slant height

  A = 2(8 m)(22 m) = 352 m²

To convert centimeters to inches, we multiply the measurement in centimeters by 2.54. identify the type of relation between cent
Westkost [7]
Hey there! Hello!

This can be represented by the equation y=2.54x, where:

y=measurement in inches
x=measurement in cm

You can plug any value into this problem to reveal that this is a linear function. I provided a graph of this to further prove the point. 

Hope this helped you out, feel free to ask any additional questions if you need further clarification! :-)

Given: sin theta=2/3 and is in the second quadrant; evaluate the following expression. sin 2 theta
Dmitry [639]

Answer:The answer to your question is 3. 0

Step-by-step explanation:

Process

1.- Find the cos a

  Opposite side = 5

  Hypotenuse = 13

  Adjacent side = ?

  Adjacent side² = 13² - 5²

                          = 169 - 25

                          = 144

 Adjacent side = 12

cos a = 12/13

2.- Find the sin b

sin b = 5/13

3.- Use the formula below to find sin(a + b)

              sin (a + b) = sina cosb  + sin b cos a

- Substitution

              sin (a + b) = (5/13)((-12/13) + (5/13)/12/13)

- Simplification

              sin (a + b) = -60/169 + 60/13

- Result

              sin(a + b) = 0
