На Гэ-паскале можно написать так:
program math;
var perimeter, a: real;
begin
write('Vvedite perimeter: ');
read(perimeter);
a := perimeter / 4;
writeln('r vpisannoi okruzhnosti = ', a / 2:0:2);
writeln('R opisannoi okruzhnosti = ', sqrt(2) / 2 * a:0:2);
readln();
readln();
end.
Var s,n:integer;
begin
repeat
readln(n);
if (n mod 3=0) and (n<10) then s:=s+n;
until n=0;
writeln('S=',s);
<span>end.</span>
Вот так, через логарифм:
exp(ln(a+1) / 3)
