Answer 1

For the graph one, you have to make a triangle.

Answer 2

volume of cylinder \[=\pi r^2 h\]
\[volume~of~sphere=\frac{ 4 }{ 3 }\pi r^3\]

Answer 3

For the triangle one: a^2 + b^2 = c^2
9^2 + b^2 = 41^2
81 + b^2 = 1681
-81
b^2 = 1600
b = 40.

Answer 4

104^2 + 78^2 = c^2.

Answer 5

10816 + 6084 = c^2
16900 = c^2
sqrt(16900) = c
c + 78 = the total.

Answer 6

130 + 78 = ?

Answer 7

Just add them, please..

Answer 8

208

Answer 9

Thank you, correct. That is your answer.

Answer 10

for the first one right

Answer 11

For the triangle one: a^2 + b^2 = c^2 9^2 + b^2 = 41^2 81 + b^2 = 1681 -81 b^2 = 1600 b = 40. This is for the one under the graph one.
