The circumference of a circle is 9.45cm. Find the length of the diameter.
Give your answer rounded to 2 DP.​

D = 3 cm

Step-by-step explanation:

Given that,

The circumference of a circle is 9.45cm.

We need to find the length of the diameter.

The formula for the circumference of a circle is given by :

We know that, Diameter = 2r

So,

So, the length of diameter is equal to 3 cm.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
