6/10 + 7/12 = 142/120 = 71/60 = 1.18 (One whole number, and 11/60)
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%
