Acone is inscribed in a cylinder. a square pyramid is inscribed in a rectangular prism. the cone and the pyramid have the same volume. part of the volume of the cylinder, v1, is not taken up by the cone. part of the volume of the rectangular prism, v2, is not taken up by the square pyramid. what is the relationship of these two volumes, v1 and v2?

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
