A farmer wants to build a new grain silo. The shape of the silo is to be a cylinder with a hemisphere on the top, where the radi

notsponge [240]

Answer:

The radius of the silo should be $16\ ft$

Step-by-step explanation:

we know that

The volume of the grain silo is equal to the volume of the cylinder plus the volume of a hemisphere

$V=\pi r^{2} h+\frac{4}{6}\pi r^{3}$

we have

$V=35,500\pi\ ft^{3}$

$h=4D=8r$

substitute the values and solve for r

$35,500\pi=\pi r^{2} (8r)+\frac{4}{6}\pi r^{3}$

Simplify

$35,500=r^{2} (8r)+\frac{4}{6}r^{3}$

$35,500=8r^{3}+\frac{2}{3}r^{3}$

$35,500=\frac{26}{3}r^{3}$

$r^{3}=35,500*(3)/26$

$r=16\ ft$

All three angles of a triangle add up to 180 degrees.

$\sf 146+x=180$

Subtract 146 to both sides:

$\sf x=34\textdegree$

So your answer is B.
