Answer»

Solution:-

first HEMISPHERE length=π×0.5=0.5πcm

second hemisphere=π×1=πcm

third hemisphere length=π×1.5=1.5πcm

fourth hemisphere length=π×2=2πcm

here we are seeing that AP is fromed of COMMON DIFFERENCE 0.5π

length of.spiral=sum of 15terms of this AP

length of spiral=15/2(2×0.5π+14×0.5π)cm

=15×4π=60πcm

{sorry for mistake}
