Question

HEEEELP!!!!!!: An icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 120 mm. The icicle drips at a rate of 75mm^3 per minute. How long will it take the icicle to completely melt? USE 3.14!
A. 5.1 MIN
B. 7.5 MIN
C. 15.1 MIN
D. 33.9 MIN

Answer 1

Answer:

d:33.9

Step-by-step explanation:

Answer 2

Find the volume of the icicle using the formula V = PI x r^2 x h/3

Volume = 3.14 x 4.5^2 x 120/3

Volume = 3.14 x 20.25 x 40

Volume = 2543.4 cubic mm.

Now divide the total volume by the drip rate:

2543.4 / 75 = 33.9 minutes.

The answer is D.
