Answer:
D. No, the should have canceled out in step 4 making the correct answer 5.5mm.
Step-by-step explanation:
All the steps that Arden took were correct up until the last step:
1. V = Bh ⇒ 88 =
*4^2 * h = 16
2. Divide by 16 from both sides: h = 88
/ 16
= 88/16 = 5.5
Arden forgot to cancel out the pi from both the numerator and denominator, so her answer should have been 5.5 mm, not 5.5 mm.
Thus, the answer is D.
Hope this helps!
