To determine the hypotenuse, use the formula a^2 + b^2 = c^2.

Place 80 as "a" and 39 as "b". Your formula should look like 80^2 + 39^2 = c^2.

Next, plug this into your calculator to get 7921. Then square root 7921.

Answer: 89

Arden calculated the height of a cylinder that has a volume of 88π mm3 and a radius of 4 mm. V = Bh 1. 88π42(h) 2. 88π = 16π(h)
inysia [295]

Answer:

D. No, the \pi 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\pi = \pi*4^2 * h = 16\pi h

2. Divide by 16\pi from both sides: h = 88\pi / 16\pi = 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\pi mm.

Thus, the answer is D.

Hope this helps!
