Question

a) the radius of a circle whose diameter is 56 cm​

Answer 1

Step-by-step explanation:

Radius of a circle is half of its diameter

diameter=56

radius=1/2 of diameter

=1/2 of 56

.the radius of circle is 28 cm

Answer 2

We know,

$\huge \text{Radius = } \rm \frac{Diameter}{2}$

So,

• Diameter = 56 cm (Given)

$\therefore \: \: \sf{radius} = \frac{56}{2} \: \: = \red{28 \: cm }$
