Answer:
Correct option: fourth one -> 254 cubic inches.
Step-by-step explanation:
The volume of a cylinder is given by the equation:
To calculate the internal volume of the pipe, we should use its internal radius.
The external radius of the pipe is half of the diameter, and the internal radius is the external radius minus the thickness of the pipe, so we have:
Then, using the internal radius in the volume equation, we have that:
So the correct option is the fourth one: Volume is approximately 254 cubic inches.

<u>Answer:</u>
The correct answer options are A, B, C and D.
<u>Step-by-step explanation:</u>
A. Leg-angle (LA):
According to this theorem, if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.
B. Hypotenuse-leg (HL):
If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
C. Hypotenuse-angle (HA):
If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.
D. Leg-leg (LL):
If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
Answer:
26.75 units ^2
Step-by-step explanation:
Since the shape is complex, divide it into 3 right angled triangles and one square. Find the area of these individual shapes first, then fin the sum of these area to calculate the ultimate area of e complex shape:
Triangle 1 = 1/2 x 2 x 5 = 5 units ^2
Triangle 2 = 1/2 x 2 x 2 = 2 units ^2
Triangle 3 = 1/2 x 3.5 x 9 = 15.75 units ^2
Square = 2 x 2 = 4 units squared.
Now add all these up 15.75 + 2 + 5 + 4 = 26.75 units squared.
Hope this helps
