The formula for to find the area of a cylinder is 2*3.14*r*h+2*3.14*r^2 so the area of the cylinder is 395.84 cm. To find the area of the balls, which are spheres, is 4*3.14*r^2, which equals a total area of 113.1 for one ball. Multiply that by 3 because there are three balls. That'll give you 339.3. Now you'll do 395.84cm-339.3cm=56.54. Now round that to the nearest whole number which will give you 57. The answer is 57cm.

That's the expression. ^^ And yesterday's temperature is 57 because, 68 degrees (Today's temperature) minus 11 degrees (how many degrees colder it was yesterday) is equal to 57 degrees (Yesterday's Temperature).
