Find the volume and surface area of each of the following.(nearest hundredth)

Volume = pi r^2 h

= pi * 25^2 * 55

= 107,992.25 ft^3 answer ( to nearest hundredth)

Surface area = 2pi r^2 + 2pi r h

= 3296.991 + 8639.380

= 11,936.37 ft^2 to nearest hundredth

8/21 part

Step-by-step explanation:

Given that,

A franchise is owned by three people. The first owns 1/3 of the business and the second owns 2/7 of the business.

We need to find the fractional part of the business is owned by the third​ person. It can be calculated as follows :

Hence, 8/21 part of the business is owned by the third​ person.
