Find the radius of a circle whose circumference 15 CM​

Answer»

Answer:

The radius of the CIRCLE is 2.39 CM.

Step-by-step explanation:

The FORMULA to compute the CIRCUMFERENCE of a circle is:

Circumfmerence=2\pi <klux>R</klux>

It is provided that the circumference is 15 cm.

Compute the value of radius, r as follows:

Circumference=2\pi r\\15=2\pi r\\r=\frac{15}{2\pi}\\ =\frac{15}{2}\times\frac{7}{22} \\=2.39

Thus, the radius of the circle is 2.39 cm.
