(A) The amount of shaved ice inside the cone is
______ π cubic inches.

(B) The amount of shaved ice on top of the cone is
______ π cubic inches.

(C) The total amount of shaved ice used to make the cone is
______ π cubic inches.

Answers

Answer:

(A) The amount of shaved ice inside the cone is 2.625π cubic inches.

(B) The amount of shaved ice on top of the cone is 2.25π cubic inches

(C) The total amount of shaved ice used to make the cone is 4.875π cubic inches.

Step-by-step explanation: I got the answers wrong on Time4Learning, Then it told me the correct answers. I hope this can help someone else get it correct!

The amount of shaved ice inside the cone and on top of the cone is 2.625 π and 2.25 π cubic inches. Then The total amount of shaved ice used to make the cone is 4.875 π cubic inches.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Ice cream is the combination of the cone and hemisphere.

Height of cone (h) = 3.5 in

Radius of come and hemisphere (r) = 1.5 in

(A) The amount of shaved ice inside the cone will be

[tex]\rm Volume\ of \ cone = \dfrac{1}{3} \pi r^2 h \\\\Volume\ of \ cone = \dfrac{1}{3} \pi 1.5^2 * 3.5\\\\Volume\ of \ cone = 2.625 \ \pi[/tex]

The amount of shaved ice inside the cone is 2.625 π cubic inches.

(B) The amount of shaved ice on top of the cone will be

[tex]\rm Volume\ of \ hemisphere= \dfrac{2}{3} \pi r^3 \\\\Volume\ of \ hemisphere= \dfrac{2}{3} \pi 1.5^3\\\\Volume\ of \ hemisphere= 2.25 \ \pi[/tex]

The amount of shaved ice on top of the cone is 2.25 π cubic inches.

(C) The total amount of shaved ice used to make the cone will be

[tex]\rm Total\ amount = Volume\ of \ hemisphere + Volume\ of \ cone\\\\Total\ amount = 2.625+ 2.25 \\\\Total\ amount = 4.875[/tex]

The total amount of shaved ice used to make the cone is 4.875 π cubic inches.

Answer:

x = 30°

Step-by-step explanation:

m∠ONK = 180° (straight angle)

∠ONM + ∠MNL + ∠LNK = 180° (supplementary angles)

105° + 45° + m∠LNK = 180° (substitution)

m∠LNK = 30°   (algebra)

m∠LNK + m∠NLK + m∠LKN = 180°   (sum of interior angles of a triangle)

30° + 90° + 2x = 180° (substitution, m∠NLK = 90° bc supplementary angles; other supp. angle is 90°)

120° + 2x = 180°

2x            = 60°

x              = 30°
