Surface area of hemisphere = 2*pi*r^2

=2*pi*11^2

=242pi

Surface area of cone = pi *r*h

=11pih

Total surface area = 11pi(22+h) sq cm


Volume

{{{V[hemisphere] = (2/3)pir^3}}}

=(2662/3) pi

{{{V[cone] = (1/3) pi*r^2*H}}}

=(1/3)pi(121)*H

=(121/3)pi H

Total volume = {{{(121/3)piH+(2662/3) pi}}}

= {{{(121/3)pi(H+22) cm^3}}}
