mojhsa [17]

The correct equation is:

216 = \frac{7}{8} \times x - 8

The volume of second cylinder is 256 centimeter cubed

<em><u>Solution:</u></em>

Given that,

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder

The first cylinder’s volume is 216 centimeter cubed

From given,

Let "x" be the volume of second cylinder

Therefore,

Volume of first cylinder = 7/8 of the volume of a second cylinder - 8

216 = \frac{7}{8} \times x - 8

216 = \frac{7x}{8}-8\\\\216 = \frac{7x-64}{8}\\\\7x - 64 = 8 \times 216\\\\7x - 64 = 1728\\\\7x = 1728 + 64\\\\7x = 1792\\\\Divide\ both\ sides\ by\ 7\\\\x = 256

Thus the volume of second cylinder is 256 centimeter cubed
