Answer:
surface area of solid = csaof cone + csa of hemisphere
csa of cone = pie×radius×slant height
slant height =root of (24)^2+(10)^2
= rootof 576+100
=root of 676
= 26
csa of cone = 22/7×10×26
= 817.142
csa of hemisphere = 2 × pie× (radius)^2
= 2×22/7×100
= 4400/7
= 628.571
surface area = csa of cone +csa of hemisphere
= 817.142 + 628.571
= 1445.713
