Answer 1

i hope it will help you

Answer 2

FIRST SPHERE DIAMETER IS 2cm RADIUS IS 1cm so the volume of 1st sphere is V1= 4/3*pi*r^3= 4/3*22/7*(1)^3 LIKE THIS WAY 2nd sphere volume V2= 4/3*22/7*(6)^3 (diameter =12 so radius will be 6) and volume of 3rd sphere V3 = 4/3*22/7*(8)^3 (diameter=16 so radius=8) SO THE FINAL SPHERE VOLUME will be V=V1+V2+V3 or V= 4/3*22/7*(1+6^3+8^3) RADIUS OF FINAL SPHERE R (if) -----------4/3*22/7*R^3= 4/3*22/7*(1+6^3+8^3) or R^3= 1+ 216+512 or R=(1+216+512)^1/3 =9cm ANSWER
