Answer 6

well how did you do it, and we will find out you did it wrong :D

Answer 7

a

Answer 8

lol, no.
im right.

Answer 9

I like confidence!

Answer 10

volume of cuboid = 5 x 6 x 11= 330 mm^3
now tricky part
the transversal cylinder
area of base 1/2 pi (2)^2 = 6.28 mm ^2
height = 11
vol of cylinder = 6.28 x 11
= 69.11 mm ^3
330 + 69.11= 399.11 mm^3

Answer 11

nope, youre area of a circle is incorrect, plus its best if you find the area of the cylinder THEN divide by 2

Answer 12

you want pi*r^2 which is pi*(2.5)^2
then multiply by 11 and divide by 2

Answer 13

excuse me, my I found the volue of the semi cylinder. :P

Answer 14

its 215mm3

Answer 15

wait the radius is 2.5 not 2
so
area of base = 1/2 pi (2.5 )^2
9.8 is the base area
9.8 x 11 = 107 .99

330 + 107.99=
437.99 = 438
