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.

Question asked:

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

Solution:

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.

OF bisects EOF. EOF=y+30 and FOG=3y-50. solve for y.

Alexeev081 [22]

It always helps to draw a picture. Given the information, Segment OF is the center line that is bisecting this angle.

Since it's bisecting (cutting in half)... we can simply set the two angles equal to each other.

y+30=3y-50
-2y+30=-50
-2y=-80
y = 40

C)40.
