Aballoon is expanded to the same volume as that of a human head. do an order-of-magnitude estimate of the volume of this balloon in cm^3 a. 100cm^3 b. 1,000,000cm^3 c. 10cm^3 d. 1,000cm^3

Volume of head = 1000 cm^3

Explanation:

 The head of a normal person can be assumed as a sphere with radius 10 cm.

 Volume of sphere, where r is the radius.

 We have approximate radius = 10 cm.

  Approximate volume of head

 In the given options the closest value to the approximate volume is 1000 cm^3.

 So, volume of head = 1000 cm^3

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
