Question

find the radius of a circle whose diameter is 8 centimetre​

Answer 1

Step-by-step explanation:

diameter of a circle=8cm

$lets \: x \: be \: the \: radius \: of \: a \: circle \\ radius = \frac{diameter}{2} \\ x = \frac{8}{2} = 4cm$

radius of a circle =4cm

Answer 2

Answer:

Since the diameter of the circle =8

Then radius =4

Step-by-step explanation:

Diameter is the biggest chord of the circle

And radius is the length from the centre

Diameter passes through the centre

Therefore radius=diameter÷2

D=8

R=D÷2

=8÷2

=4
