Answer:
≈ 78.55 cm
Step-by-step explanation:
Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is
=
, that is
=
( cross- multiply )
110C = 8640 ( divide both sides by 110 )
C = ≈ 78.55 cm ( to 2 dec. places )
We have to functions, namely:
So the problem is asking for the smallest positive integer for
so that 
is greater than the value of 
, that is:
Let's solve this problem by using the trial and error method:
So starting from 1 and increasing it in steps of one we find that:
when
That is, the smallest positive integer for so that the function is greater than is 4.
So the problem is asking for the smallest positive integer for
Let's solve this problem by using the trial and error method:
So starting
when
That is, the smallest positive integer for
