Answer:

The radius of the circle with circumference 22cm is 3.5 cm

Step-by-step explanation:

The circumference of circumference of a circle is the distance of its closed boundary.

The circumference of a circle with radius r is given by the formula:

$C = 2\pi r$

Given

C = 22cm

Putting the values in the formula

$22 = 2 * \frac{22}{7} * r\\22 = \frac{44}{7} * r\\r = \frac{7}{44} * 22\\r = \frac{7}{2}\\r = 3.5cm$

Hence,

The radius of the circle with circumference 22cm is 3.5 cm

Using it's concept, the range of the function is given as follows:

0 ≤ m ≤ 1200.

<h3>What is the range of a function?</h3>

The range of a function is the set that contains all possible output values for the function.

For this problem, we have to consider these two bullet points next, considering the mass is the output value of the function.

The smallest possible mass for the substance is of 0 grams, as after the substance decays to 0 grams, it will not assume a negative value, it will just disappear.

The greatest possible mass for the substance is the initial mass of 1200 grams, as the substance does not adquire mass with time, it just loses it.

Considering these masses, the range of the function is given as follows:

0 ≤ m ≤ 1200.
