Carol is going to make a wooden pyramid and then paint it. She drew the net of a square pyramid as shown below to help her plan
rodikova [14]

The given pyramid's total surface area is 3. 24.0 square feet.

Step-by-step explanation:

Step 1:

To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.

There are 3 triangles and 1 square in the figure.

Step 2:

All the triangles are similar.

The surface area of a triangle = \frac{1}{2} (baselength)(height).

The similar triangles have a base length of 3 feet and a height of 2.5 feet.

The surface area of 1 similar triangle = \frac{1}{2} (3)(2.5)= 3.75 square feet.

The surface area for all the similar triangles = 3.75 (4) = 15 square feet.

Step 3:

The surface area of a square is the square of its side length. The square has a side length of 3 feet.

The surface area of the square = a^{2} = 3^{2} =9 square feet.

Step 4:

To calculate the total surface area we sum up all the individual surface area.

The total surface area = 15 + 9 = 24 square feet which is the third option.

Please help, When do you need to approximate an irrational number with a rational value? Explain your understanding and give an
disa [49]

9514 1404 393

Answer:

  in any numerical computation; numerical values can only be rational numbers

Step-by-step explanation:

Any time a number is written down as a numerical value, it is a rational number. The numerical values we give to π or e or any root, logarithm, trig function, and polynomial solution are, of necessity, rational approximations to the true value. An "exact" value for an irrational number cannot be written down, so it must be approximated any time its numerical value is needed.
