A walffle cone has a height of 7 inches and a diameter of 3 inches. What is the volume of ice cram that can be contained within

Anna [14]

Answer:

16.49 cubic inches.

Step-by-step explanation:

Given:

A waffle cone has a height of 7 inches and a diameter of 3 inches.

<u>Question asked:</u>

What is the volume of ice cram that can be contained within the cone?

<u>Solution:</u>

First of we will find the radius ;-

Diameter = 3 inches

Radius, r = $\frac{Diameter}{2} =\frac{3}{2} =1.5\ inches$

As we know:

$Volume\ of\ cone=\frac{1}{3} \pi r^{2} h$

$=\frac{1}{3} \times3.14\times1.5\times1.5\times7\\ \\ =\frac{49.455}{3} \\ \\ =16.485$

Thus, volume of ice cream will be 16.49 cubic inches.

100 POINTS! PLEASE HELP!

Semmy [17]

Apply angle bisector theorem

$\\ \sf\longmapsto \dfrac{9}{15}=\dfrac{3}{5}=\dfrac{2x-1}{3x}$

$\\ \sf\longmapsto 9x=5(2x-1)$

$\\ \sf\longmapsto 9x=10x-5$

$\\ \sf\longmapsto 10x-9x=5$

$\\ \sf\longmapsto x=5$

$\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{2.25}$

$\\ \sf\longmapsto 4(2.25)=3x$

$\\ \sf\longmapsto 3x=9$

$\\ \sf\longmapsto x=3$

Hope it helps
