When there are a number of similar calculations to do, it is convenient to program a calculator or spreadsheet to do them for you. The formula for the volume (V) of a cylinder in terms of height (h) and radius (r) is

... V = π·r²·h

You simply need to substitute the given values and determine if the result is greater than 50. For glass A, this looks like

... V = 3.14·2.25²·3 = 47.68875 . . . . . less than 50, so too small

The volumes of the other glasses are calculated in the attachment.

glass B: large enough

glass C: too small

#1. Which is equal to z3 8? A. (z - 2)(z^2 - 2z - 4). B. (z + 2)(z^2 - 2z + 4) C.(z - 2)(z^2+ 2z + 4). D. (z + 2)(z^2+ 2z - 4) #

#1. B
(z * z^2 + z * 2z + z * 4) – (-2 *z^2 – (-2) 2z – (-2) 4)
Z^3 + 2z^2 + 4z – 2z^2 -4z – 8
Z^3 + 2z^2 – 2z^2 + 4z – 4z – 8
Z^3 - 8

#2 and #3. D
(x + y)(x + 2)
x^2 + 2x + yx + 2y

#4. D.
(x - 7)(x + 7)(x- 2)
x^2 + 7x – 7x -49
x^2 + x – 49
x^2 -49
(x^2 – 49 ) (x – 2)
x^3 – 2x^2 – 49x + 98

#5. C
(y - 4) = 0
y = 4
(x + 3)= 0
x = -3

#6. A and B
