For a wire with a circular cross section and a diameter = 3.00mm calculate the following: (m means meter. mm means millimeter. cm means centimeter.) calculate the cross sectional area in mm2. calculate the cross sectional area in cm2

The cross sectional area in mm2 is 7.07

The cross sectional area in cm2 is 0.0707

Explanation:

The cross-sectional area (a) of the wire is given by;

a = x

where d is the diameter of the cross section = 3.00mm

1 => To find the cross-sectional area in , substitute the value of d = 3.00mm into the equation above as follows;

a = x

Taking to be we have;

a = x

a = 7.07

2 => To find the cross-sectional area in , first convert the diameter in mm to cm as follows;

3.00mm = 0.3cm

Now, substitute the value of d = 0.3cm into the equation above as follows;

a = x

Taking to be we have;

a = x

a = 0.0707

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
