Answer 2

Answer:

11/24 cc ; 200cc ; 144000 words

Explanation:

shape : cylinder

height : h = 7cm

diameter : d = 5mm

radius : r = 5/2 = 2.5mm = 2.5/10 = 0.25cm

words /pen : n = 330

a) volume = 1/3 π r^2 h

V = 1/3 × 22/7 × 0.25 × 0.25 × 7

V = 11/24 cc

b) V' = 1/5 L

but 1L = 1000cc then ..

V' = 1/5 L = 1/5 × 1000 = 200cc

c) since...V volume writes n words

then V' volume writes...

n' = V'/V × n

n' = 200/(11/24) × 330

n' = 144000 words
