Find the volume of the cone. round to the nearest tenth. 9 cm r = 6 cm

#12 find the value of x. #13 find the value of the variable.

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1

What is the volume of the cone to the nearest cubic millimeter? (use π  = 3.14) a) 46 mm3 b) 128 mm3 c) 183 mm3 d) 275 mm3 diameter = 5 mm height = 7 mm how do you do this problem step by step?
