Question

the diameter of the circle is 4 centimetre to calculate the area that is purple​

Answer 1

Answer:

area of square=4+4=8cm(side)

ar=8^2=64cm^2

area of 1 circle =π×4

area of 4 circle=16π

so area of purple=64-16π=4-π=4-3.14=0.86

Answer 2

Answer:

to find the area of the circle we need to know the radius

So,

radius=4/2= 2cm.

so the formula of the area of the circle is

$\pi \: r {?}^{2}$

so 22/7×2×2= 88/7= 12.566
