Find the surface area of this composite solid.

Mathematics
1 answer:
Nataly_w [17]3 years ago
7 0

Answer: C

Step-by-step explanation:

The surface area of a pyramid = A + 1/2ps

Where A = area of the base

P = perimeter of base

S = slant height.

A = 4 × 4 = 16 m^2

P = 4L = 4 × 4 = 16 m

S = 3m

Surface area = 16 + 1/2 × 16 × 3

Surface area = 16 + 24

Pyramid surface area = 40 m^2

The surface area of the cuboid = LB + 2LH + 2BH

Where

B = width

H = height

L = length

Substitute all the parameters into the formula

Surface area = 4×4 + 2(4×5) + 2(4×5)

Surface area = 16 + 40 + 40

Surface area = 96 m^2

To Find the surface area of this composite solid, you will add the pyramid surface area to the cuboid surface area. That is

Total surface area = 40 + 96 = 136m^2

Therefore, the surface area of this composite solid is 136 cubic meters

Pls help!!<br> 94 + 8r - 7
Fofino [41]

Answer:

87 + 8r

Step-by-step explanation:

We have a variable that we cannot simplify further:

8r

But we have two numbers that we can simplify:

94 - 7 = 87

Then we add those together:

8r+87

Does this graph show a function?
Montano1993 [528]

9514 1404 393

Answer:

  A

Step-by-step explanation:

A vertical line intersects the graph in <em>more than one place</em>. As a consequence, we say the graph "fails the vertical line test." When the test fails, the graph is not a graph of a function.
