Assuming that this problem is asking about a cylinder, the volume can be found using the formula (pi)(r)^2 * h (area of the circle * height) and the surface area can be found using the formula (2)(pi)(r)h (circumference of the circle * height).
Hello : let A and B two points in the first line calculate the slope : <span>: (YB - YA)/(XB -XA) </span>let C and D two points in the second line calculate the slop (YC - YD)/(XC -XD) you are slope
She would multiply the rate by the years to find the average rise in water levels, or 1.8 times 6.2 = 11.16. To find the difference between the water levels, she would subtract -13.64 from 11.16.
