1956.57

VOLUME OF SHAPE = VOLUME OF CYLINDER + VOLUME OF CUBOID

= Pie r^2 h + L ×B × H

pie = 22/7

r of cylinder is 4 as 8/2

h = 9

just put the values in pie r^2 h

u get

22/7 × 4 × 4 × 9

20.57

volume of cyli der =

16 ×11 × 11

= 1936

hence add them both

1936 + 20. 57

we get 1956.57 in.^2

GOOD LUCK FOR THE FUTURE! :)

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
