Cylinder A -
Surface Area:
<em>A = 2πrh + 2πr^2</em>
<em>A = 2 · π · 5 · 7.5 + 2 · π · 25 ≈ 392.69908</em>
<em>A = </em>392.7 cm^2
Volume:
<em>V = πr^2h</em>
<em>V = π · 25 · 7.5 ≈ 589.04862</em>
<em>V = </em>589 cm^3
Cylinder B -
Surface Area:
<em>A = 2πrh + 2πr^2</em>
<em>A = 2 · π · 3.5 · 5 + 2 · π · 12.25 ≈ 186.92476</em>
<em>A = </em>186.9 cm^2
Volume:
<em>V = πr^2h</em>
<em>V = π · 12.25 · 5 ≈ 192.42255</em>
<em>V = </em>192.4 cm^3

Answer:
$7,250
Step-by-step explanation:
14000 + 500 = 14500 - reverse the subtraction
14500/2 = 7250 - do the opposite of multiplication
Lets check 7250*2 = 14500 - 500 = 14,000
