Answer:
20 . D joint variation
40. A
41. D 76cm
Step-by-step explanation:
20. The formula for the volume of a cylinder, is another example of jointvariation. The volume of the cylindervaries jointly with the square of the radius and the height of the cylinder. The constant of variation is .
40. Line QS is congruent to line PR
41. Perimeter of a Parallelogram
P = 2(a+b)
P = 2(15 cm +23 cm)
P = 2(38 cm)
P = 76 cm
