The circumference of the circle with a radius of 49mm is 308mm
<h3>How to find the circumference of a circle?</h3>
The circumference of the circle is also known as its perimeter. The formula is expressed as:
C = 2pi r
r is the radius = 49mm
pi = 22/7
Substitute
C = 2 * 22/7 * 49
C = 2 * 22 * 7
C = 308mm
Hence the circumference of the circle with a radius of 49mm is 308mm

<span>Multiplication with fractions is similar to multiplication with whole numbers in that you are often finding the product of groups of items. They are different in that you can multiply with fractions to find parts of an amount.</span>
<span>Graphs can be used to represent periodic data because you can show rise and fall of something and express situations that may be tough to show in writing.</span><span>
In the case that the periodic data is on the range of the function (the y axis)
You can use functions to represent periodic data:
example y=sin(x)</span>
