i think the answer should be
14 (sqr) - (16 π +4 )
on solving
196 - 54.24 = 141.76.
14 (sqr) - (16 π +4 )
on solving
196 - 54.24 = 141.76.
waRRi0r:
we have 4 semicircles = 4 * (2π)
= 8π
while cutting a semicircle we create a smaller sqaure at center of the fig
this smaller sqr each side will be equal to diameter of a semicircle
that is 4 cm
so the area of the center smaller square = 4^2 = 16
so the total unshaded would be all semicircle area and this center smaller area
which is = 8π + 16
for shaded part deduct this from entire area we calculated that is 196
so 196 - (8π +16)
