Steps to solve this-- Find the percent of increase from 380 to 440. Round to the nearest tenth of a percent if necessary. 13.6%
OLga [1]
If 380 would be 100%

Then use rule of 3

380 ______ 100%

440 ______ y

380y = 440×100%

Travka [436]

Answer:

V = \frac{400}{3}\pi

V = \pi r^{2} \frac{h}{3}

Substitute values given:

V = \pi (5^{2} )(\frac{16}{3})

V = \pi (25)(\frac{16}{3} )

V = \pi \frac{400}{3}

V = \frac{400}{3}\pi
