6. The formula for the volume of a cone is V=1/3 tr^2 h. (Please note: The formula is read as, "Volume equals one-third pi radius squared times
height"). The radius, r, of the cone may be expressed as *
O 1.3V(V/rth)
O 2.1/3 (V/th)
O 3. V(V/3rth)
O 4. V(3V/rth)

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

According to the data set, where should the upper quartile line of the box plot be placed?

Gravel is being dumped from a conveyor belt at a rate of 25 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. how fast is the height of the pile increasing when the pile is 14 ft high? (round your answer to two decimal places.) ft/min
