Maru [420]

The percentage change in volume from cylinder A to cylinder B; D: 100%

<h3>How to find the percentage change in Volume?</h3>

Formula for Volume of a Cylinder is;

V = πr²h

Thus, volume of Cylinder A is;

V_a = π * 7² * 5

V_a = 245π

Thus, percentage change in volume is;

[245π/(490π - 490π)] * 100%

Percentage change in volume = 100%

0.9(x+1.4)−2.3+0.1x=1.6

IgorC [24]

so what you do is distribute the 0.9 to x and 1.4 to get 0.9x+1.26 then combine like terms 1.9x - 1.04= 1.6 then add 1.04 to both sides to get 1.9x = 2.64 divide 1.9 to both sides
