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.

Choose the point-slope form of the equation below that represents the line that passes through the points (-6, 4) and (2, 0).
Pavlova-9 [17]
Point slope form
y-y1=m(x-x1)
slope=m
a point is (x1,y1)

slope=(y2-y1)/(x2-x1)
given
(-6,4) and (2,0)
slope=(0-4)/(2-(-6))=-4/(2+6)=-4/8=-1/2

a point is (-6,4)
x1=-6
y1=4

y-4=-1/2(x+6)

rjkz [21]
I'm assuming the box is a rectangular prism:
They're asking for the surface area so the answer should be 48*2 + 192*2 + 36*2 since it has 6 faces so S.A. = 552 square in.
