    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=\[\frac{ 4 }{ 3 }pir^3\]

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

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

    \[Diameter=\frac{ radius }{ 2 }\] |dw:1442091259695:dw| 1 meter=1.0 x 10^6 micrometers so 1 micrometer=1.0 x 10^-6 meters

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

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

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

    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.

    \[\frac{ micrometers }{ 1 }\times \frac{ 0.00001 }{ 1micrometer }\] Convert to meters* from above.
