Question

Need help!!
Diameter of a sphere is measure in 2.14 micro- meter. Calculate the circumference and volume of a sphere in the meter.

Answer 1

Convert 2.14 micrometer to meters.
Find the radius by dividing the diameter by 2
Use it for the formula for the volume and circumference of a sphere.
Circumference of a sphere=2(pi)r
Volume of a sphere=\[\frac{ 4 }{ 3 }pir^3\]

Answer 2

Circumference of a sphere=2(pi)r
=2 (3.14)(2.14)
=1.34

Answer 3

Like I said:
1. Convert 2.14 micrometer to meters.
2. Find the radius by dividing the diameter by 2

Answer 4

\[Diameter=\frac{ radius }{ 2 }\]

1 meter=1.0 x 10^6 micrometers
so 1 micrometer=1.0 x 10^-6 meters

Answer 5

then the circumference be =2(3.14)(1.07)
=6.7

Answer 6

@Shalante

Answer 7

v= 4/3 pie r^3
v= 4/3(3.14)(1.07)^3

Answer 8

Convert!!

Answer 9

Convert to micrometer

Answer 10

1 meter=1.0 x 10^6 micrometers
so 1 micrometer=1.0 x 10^-6 meters

Answer 11

oh ok then it be 6.72 x 10^-6 meters

Answer 12

rightz?

Answer 13

but know for the volume

Answer 14

is it be 4*pi*1.07^3

Answer 15

sorry it be 4/3*pi*1.07^3

Answer 16

Hey, my explanation above says
Convert 2.14 micrometer to meters.
Find the radius by dividing the diameter by 2
Use it for the formula for the volume and circumference of a sphere.
Circumference of a sphere=2(pi)r
Volume of a sphere=(4/3)(pi)r^3

You convert first before plugging anything or you will get messed up because there is an exponent.

Answer 17

Do the steps in order please.

Answer 18

\[\frac{ micrometers }{ 1 }\times \frac{ 0.00001 }{ 1micrometer }\]

Convert to meters* from above.

Answer 19

ok I get the answer

Answer 20

Show me your steps and answer.

Answer 21

ok wait a sec

Answer 22

V=43πr3 V=43π(1.07×10−6 m)3
V=43π 1.073×10−6⋅3 m3
V=5.13×10−18 m3

Answer 23

(4/3)(pi)^3 you mean?

Answer 24

yeah

Answer 25

I got 5.12 x 10^-18 but close enough.

Answer 26

And your first one?

Answer 27

that is C= 2*pi*1.07 um
= 6.7x 10^-6

Answer 28

Yea, it looks correct

Answer 29

ok thanks a lot
