Liam and Tehya are trying to determine whether ΔABC and ΔEFD can be proven congruent through rigid motions. Liam says that ΔABC

≅ ΔEFD because ΔABC can be reflected over the y-axis to create ΔEFD. Tehya says that ΔABC ≅ ΔEFD because ΔABC can be rotated 90° clockwise about the origin to create ΔEFD. a coordinate grid with triangles ABC and DEF at A at negative 7 comma 2, B at negative 3 comma 6, C at negative 2 comma 1, D at 2 comma 1, E at 3 comma 6, and F at 7 comma 2 Who is correct? Liam only Tehya only Both Liam and Tehya Neither Liam nor Tehya

Ng ne Volume of a Cone
AnnyKZ [126]
Answer: height = 6, radius = 8, Volume = 401.92

Explanation:
Height = 6 given

Find radius:

Use Pythagorean’s theorem to find the side of the right triangle:

a^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 10^2 - 6^2
b^2 = 100-36
b^2 = 64
b = 8

And since length b is also the radius of the circle then radius = 8

Find volume:

V = pi x r^2 x h/3

V = 3.14 x 8^2 x 6/3

V = 3.14 x 64 x 2

V = 401.92

Helppppp with this. What do I have to do?
vaieri [72.5K]

You need to use the grids to draw rectangles which meet the requirements to help you put the answers in on the right.


1) Short side of 7 and long side of 9.

2) Short side of 9 and long side of 10.

3) Short side of 3 and long side of 8.

4) Short side of 4 and long side of 9.

5) Short side of 3 and long side of 5.

6) Short side of 6 and long side of 8.

7) Short side of 1 and long side of 2

8) Both sides 10 (this is technically a square).

9) Short side of 6 and long side of 9.

10) Short side of 7 and long side of 8.

11) Short side of 2 and long side of 3.

12) Short side of 6 and long side of 9.


You can draw these a few different ways to still get a correct result, so above are just one way of doing it.
