Question

in the figure given below, AC and BD are two perpendicular diameters of a circle with centre O. If AC= 16 cm, calculate the area and (take pi= 3.14) please give step by step explanation.​

Answer 1

Answer:

hey you want area of whole circle ??

then answer will be as below

area of circle = pir²

here, d=16

we know r=d/2

therefore

r=16/2=8

therefore

area=8²x3.14

=64x3.14=200.96

Answer 2

Answer:

200.96

Step-by-step explanation:

AC=16cm,which is diameter of circle

so AO=8cm,which is radius of circle

area of circle =πr²

                     =3.14×8²

                    =200.96
