Answer:
1658.3
Step-by-step explanation:
the perimeter of a semi - circle is simply half the circumference of a circle.
that is ;
1 / 2 ( pi ( r² ) )
where;
pi = 3.14 ( this is a constant that should be known and also equals 22 / 7 )
r = radius ( or half a diameter )
in our question, we are given a diameter with no radius
this means that we will have to halve the diameter to give us our radius
that is;
d = 65cm
r = 65 / 2
r = 32.5
so, using our formula;
1 / 2 ( 3.14 ( 32.5² ) )
1 / 2 ( 3.14 ( 1056.26 ) )
1 / 2 ( 3316.65 )
1658.3125
rounded to 1 DP;
1658.3
