Answer:
[tex]200\pi[/tex] or 628.3185
Step-by-step explanation:
Area of a semicircle is equal to [tex]\frac{\pi r^{2}}{2}[/tex]. So, when the radius is 20, the area of the semicircle will be [tex]\frac{\pi (20)^{2} }{2} =\frac{400\pi }{2} =200\pi =628.3185[/tex].

SOS MSENVJBQJBVKJQBH I NEED HELP- math is way to hard i think im gonna drop out lols 4(5 + 2x) – 5 = 3(3x + 7)
Answer: x= -6 I'm not sure about this though.
Step-by-step explanation:
Answer:
[tex]4(5 + 2x) - 5 = 3(3x + 7)[/tex]
[tex]20 + 8x - 5 = 9x + 21[/tex]
[tex]15 + 8x = 9x + 21[/tex]
[tex]9x + 21 = 15 + 8x[/tex]
[tex]9x - 8x = 15 - 21[/tex]

The storage box for a flag is in the shape of a triangular prism. What is the surface area of the box?
*see attachment for the diagram of the triangular prism box
Answer:
528.8 in.²
Step-by-step explanation:
Surface area of triangular prism = 2(BA) + P*H
Area of triangular base (BA) = ½*b*h
b = 24.5 in.
h = 12 in.
BA = ½*24.5*12 = 147 in.²
Perimeter of triangular base = 24.5 + 17.1 + 17.1 = 58.7 in.
Height of prism = 4 in.
Plug in the values into the surface area formula:
Surface area of prism = 2(147) + 58.7*4
= 294 + 234.8
= 528.8 in.²
