Question

The diameter of a red blood cell is about 3 x 10-4 in. What is its diameter in centimeters?

Answer 1

The diameter of red blood cell
`8* 10^(-4)cm`

Step-by-step explanation:

1 in = 2.54 cm

So,
`3* 10^(-4)in = (3* 10^(-4))* 2.54 cm`

=
`8* 10^(-4)cm`

Hence the diameter of red blood cell
`8* 10^(-4)cm`
