The base of a solid is a region in the first quadrant bounded by the x-axis, y-axis, a the line x + 2y = 8, as shown in the figure above. If cross sections of the solid
perpendicular to the x-axis are semicircles, what is the volume of the solid? Be sure
to round your answers to 3 places past the decimal.

answer: check all that apply, where the options?

step-by-step explanation:

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

the correct option is b

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
