Rotating the decagon by a multiple of carries the decagon onto itself. therefore, a rotation
of_ counterclockwise will carry the decagon onto itself. we can reflect the decagon
different ways, including ways using the lines of symmetry that pass through the
midpoints of two opposite sides.

think the answer would beb

the answer to this is a. a^2 + b^2 = c^2

answer is  

a.

16.1

hope you got it chief.

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
