The area of a triangle:
$A_\Delta=\dfrac{bh}{2}$
We have:
$A_{\Delta}=234.4\ ft^2.\\\\h=16\ ft.$
substitute:
$\dfrac{16b}{2}=234.4\\\\8b=234.4\ \ \ |:8\\\\b=29.3\ ft.$
Answer: 29.3 ft.

Answer:

j : 7327

Step-by-step explanation:

Split the figure into three parts 1 cylinder and hemispheres.

find the volume of each part and then in the end add them

Vol of cylinder =

$\pi \times r {}^{2} \times h \\ 3.14 \times 10 \times 10 \times 10 \\ = 3140 \\$

Find the volume of one hemisphere=

$= \frac{2}{3} \pi \times r {}^{3} \\ 2093.33$

Vol of 2 hemispheres = 2×2093.33

= 4186.66667

Total volume= 3140 + 4186.6667 = 7326.66

= 7327
