Question

One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cylinder. If the first cylinder’s volume is 216 Centimeters cubed, what is the correct equation and value of x, the volume of the second cylinder?

StartFraction 7 over 8 EndFraction x + 8 = 216; x = 182 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 196 centimeters cubed
StartFraction 7 over 8 EndFraction x + 8 = 216; x = 238 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 256 centimeters cubed

Answer 1

D. StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 256 centimeters cubed

Answer 2

• D. StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 256 centimeters cubed

Explanation:

Equation for the volume and solution:

• 7/8x - 8 = 216
• 7/8x = 216 + 8
• 7/8x = 224
• x = 224*8/7
• x = 256 cm³

Correct option is D.
