Answer:

376.52 is the volume of the composite figure.

Step-by-step explanation:

Let's break this into two shapes.

A rectangular prism and a hemisphere

Volume Formula for rectangular prism: l • h • w

Volume Formula for hemisphere: (2/3)πr^3

l • h • w

10 • 4 • 8

40 • 8

320

Rectangular Prism: 320

(2/3)πr^3

2/3(3)^3

2/3(3.14)(27)

2.09333333333(27)

56.52

Hemisphere: 56.52

320 + 56.52 = 376.52

Rus_ich [418]

Answer:

$x=22\ yd$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

$\frac{x}{14}=\frac{77}{49}$

solve for x

$x=\frac{77}{49}(14)$

$x=22\ yd$

Answer:

The answer would be A

Step-by-step explanation:
