Question

What is the area and radius of a circle . whose diameter is 8 cm

Answer 1

✞︎ Given :-

Diameter of the circle = 8 cm

We know that ,

$Radius \: = \frac{Diameter}{2}$

$radius = \frac{8}{2}$

➪︎ $radius = 4 \: cm$

$area \: of \: circle = \pi {r}^{2}$

$area = \frac{22}{7} \times 4 \times 4$

➪︎ $area \: = 50.2857 {cm}^{2}$

Answer 2

Answer:

Radius:- 4 cm

Area:- 50.28 cm

Step-by-step explanation:

Radius of circle is= d/2

=8/2

=4cm

Area of Circle= 2 π radius(square).

= 50.28cm
