In part b, you found the perimeter of side aehd. what is the perimeter of any cross section that is parallel to this side?

The perimeter of any cross section that is parallel to side AEHD will be

Step-by-step explanation:

we know that

The side AEHD is a square

The perimeter of a square is equal to

where

b is the length side of the square

we have

substitute

-----> perimeter of side AEHD

therefore

The perimeter of any cross section that is parallel to side AEHD will be

The perimeter of any cross section that is parallel to side AEHD will be 12 inches.

step-by-step explanation:

1. which statement below is true for hyperbolic geometry?

answer: d  

the sum of the measures of the angles in a triangle is always less than 180 degrees.

2. identify the statement that is true in spherical geometry.

answer: d  

the sum of the measures of the angles of a triangle is greater than 180.

3. what can be said about the vertices of an equilateral triangle drawn in poincaré’s system?

answer: b  

the vertices are equidistant from the center of the circle.

4. satellites sputnik, yeltsin, and plekov often temporarily line up in order in a great circle. the circumference of the earth is 24,900 miles, and the satellites orbit at about 150 miles above the surface. if, while in a great circle, sputnik is 9,000 miles from yeltsin, and yeltsin is 10,500 miles from plekov, how far apart are sputnik and plekov?

answer: b  

6,342 miles

5. identify the statement that is true in spherical geometry.

answer: d  

two distinct lines intersect in two points.
