The volume of a cone with a height of 6 cm is 8 pi cubic centimetres. Which expression can be used to find r, the radius of the base of the cone? 6 = one-third pi (r squared) (8 pi)

8 pi = one-third pi (r) (6 squared)

6 = one-third (pi r)(8 pi)

8 pi = one-third pi (r squared) (6)

Which pair of lines is parallel? a. y=4x+1 and y+4=5 b. y=-2+x and 2y-2x=-2 c. y=1/4x + 2 and y-2=1/2x d. y=1/5x+1 and 5y+x= 10
