Ryan wants to build an enclosed clear plastic case that is shaped like a triangular prism to display his trophies. The bases of the prism are right triangles. The new case
will look like the diagram below, but it will be 1/2 the height of the prism shown in the
diagram. What is the total surface area of the plastic case?

How do you use the elimination method for this question? explain, because i really want to understand!

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough

The area (a) of a circle with a radius of r is given by the formula and its diameter (d) is given by d=2r. arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.
