Answer 2

SOLUTION

TO DETERMINE

The radius of the circle whose diameter is 36 cm.

EVALUATION

We know radius of a circle is defined as the distance from the center of the circle to any point on the circle . It is denoted by r

Again diameter of a circle is defined as the one point on a circle to another point on the circle and passing through the center

It is denoted by d

From above we see that

Radius is half of the diameter

Here it is given that diameter is 36 cm

Hence the required radius of the circle

$\sf = \dfrac{36}{2} \: \: cm$

= 18 cm
