What is the circumference of a QUATER CIRCLE if the radius of the quater circle is 2CM

To find the area of a quarter circle, you simply take a quarter of a full circle. As all quarters are equal, this means that the formula would be <span><span>π<span><span>r2</span>4</span></span><span>π<span><span>r2</span>4</span></span></span><span>.  But wait, there's more. If you notice, </span><span><span>π<span><span>r2</span>4</span>=π<span><span>r2</span>2</span></span><span>π<span><span>r2</span>4</span>=π<span><span>r2</span>2</span></span></span><span>. This coincides with the circle formula, just with half the radius. Notice anything? A quarter of a circle can be calculated in the same way a circle a quarter the size can. This means that a quarter circle is equal to a circle a quarter size. In this same way, a ninth of a circle is equal to a circle of one ninth the size.</span>

n example 3, your friend says that there is enough information to determine the numbers of solutions of the equations $3(5x+2)=1
mr_godi [17]

The number of solutions of the equations can't be determined.

<h3>How to illustrate the information?</h3>

It should be noted an equation shows the relationship between the variables. It should be noted that the question is to find the number of solutions.

From the information, 3(5x + 2) = 15x

15x + 6 = 15x

Collect like terms

15x - 15x = - 6

0 = -6

Therefore, it can be see that the friend is incorrect as the number of solutions of the equations can't be determined.
