What? is this a question? or....is it not?
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
The answer would be c = 5.
2/5 = 2/c
2/5c = 2
2c/5 = 2
2c = 2 * 5
2c = 10
c = 10/2
c = 5.
Hope this helps and happy studying :).
