Answer:
A ≈ 26.42
Step-by-step explanation:
<em><u>The shape presented is a circle, and the formula for this is:</u></em>
A = π
<em><u>The "</u></em>
<em><u>," is the radius (2.9), so plug this into the formula:</u></em>
A = π
A = π8.41
A ≈ 26.42
Answer:

Step-by-step explanation:
The surface area of right triangular prism is the sum of area of two base triangles and 3 area of side rectangles.
The area of base triangle is

where a is the length of the side of equilateral triangle. In your case, a=6 inches. Thus,

The area of side rectangle is

where h is the height of the rectangle. In your case, h=10 inches. Thus,

Hence, the surface area is

I just finished this test and the correct answer is "4x + 6y < 120" or "B"
A (b-c) = d
b-c = d/a
-c = (d/a) - b
-c = (d-ab) /a
c = (ab-d)/a
