pi*z^2*a or "pizza"

Step-by-step explanation:

The dimensions given describe a cylinder, for which the basic volume formula would be base x height.

The base would be a circle, with the radius z as given while the height is a.

The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.

Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a

Side note:

z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
