Cup A
<em><u>Formula</u></em>
V = 1/3 pi r^2 h
<em><u>Givens</u></em>
r = d/2 = 2/2 = 1 inch
pi = 3.14
h = 4 inches
<em><u>Solution</u></em>
V = 1/3 * 3.14 * 1^2 * 4
V = 4.187
Cup B
<em><u>Formula</u></em>
V = pi * r^2 * h
<em><u>Givens</u></em>
pi = 3.14
r = d/2 = 2/2 = 1
h = 6
<em><u>Solution</u></em>
V = pi * r^2 * h
V = 3.14 * 1^2 * 6
V = 18.84
<em><u>Answer</u></em>
VB - VA = 18.84 cu in - 4.187 = 14.65 = 14.7 Rounded.
Answer C
Answer: the answer to the question is a7x
Step-by-step explanation:
Answer:
2y = 3x + 21
y = 1.5x + 10.5
plug in, in the second equation
- 4x + (1.5x + 10.5) = 23
-4x + 1.5x + 10.5 = 23
-2.5x + 10.5 = 23
-2.5x = 12.5
x = 12.5/-2.5 = -5
y = 1.5 (-5) + 10.5 = 3
x = -5
y = 3
