Let C, S and H be the diameters of cell, sand and hair


Diameter of a cell: C=1 \cdot 10^{-5}m

Diameter of a grain of sand: S=2 \cdot10^{-4}m

Part A:

H=0.000025=2.5 \cdot 10^{-5} meters, because it takes 5 movements right of the decimal dot, until there is only one digit to its left.

Part B:

we are comparing S=2 \cdot10^{-4} m to C=1 \cdot10^{-5} m ,

\frac{S}{C}= \frac{2 \cdot 10^{-4}}{1 \cdot 10^{-5}}=\frac{20 \cdot 10^{-5}}{1 \cdot 10^{-5}}=20

thus S is 20 times larger than C

Part C

1m=1 \cdot10^9nm

thus,

H=2.5 \cdot 10^{-5}m=2.5 \cdot 10^{-5} \cdot 1 \cdot 10^9nm=2.5 \cdot 10^{-5+9}=2.5\cdot10^4nm

Part D.

1m=1\cdot 10^9nm\\\\1nm=\displaystyle{ \frac{1m}{10^9}=1\cdot 10^{-9}m}

thus 300 nm are written in meters as follows:

300nm= 300\cdot 1\cdot 10^{-9}m=3\cdot 10^2 \cdot 10^{-9}m=3\cdot 10^{-7}m

zimovet [89]

Answer:

Step-by-step explanation:

cylinder's height=3×(diameter of sphere)=3×6=18 cm

radius of cylinder=3 cm

volume of cylinder=π r²h=π(3)²×18=162 π cm³

volume of sphere=4/3 π(3)³=36 π cm³

reqd. empty space=162 π-3×36π=54 πcm³
