Assuming that a soap bubble is a perfect sphere, what is the diameter of a bubble containing 1,000 cm^3 of air? Round to the nea
jenyasd209 [6]

Answer:

A is correct

Step-by-step explanation:

In this question, we are concerned with. calculating the diameter of a bubble given the volume of the bubble.

Since we have assumed the bubble to be a perfect sphere, it’s volume V = 4/3 * pi * r^3

Plugging the value of V = 1000cm^3 , we have

1000 = 4/3 * pi * r^3

3000/4pi = r^3

r^3 = 238.732

r = cube foot of 238.732

r = 6.20cm

This is same as 6.2cm

FIND THE EXACT VOLUME PLEASE HELP ILL GIVE BRAINLIESTTTT
Eva8 [605]

Answer:

495 in

Step-by-step explanation:

The formula for the volume of a triangular prism is V = \frac{1}{2} · w · h · l, where w represents with, l represents length, and h represents height. Using this and plugging in the values, we can solve.

V = \frac{1}{2} · 5 · 11 · 18

V = 2.5 · 11 · 18

V = 27.5 · 18

V = 495

hope this helps :)
