Please help me out with this :) and explain if you can

Answer:

V=39.25. the height is not 6.25, 6.25 is the slope. you have to use Pythagoras theorem to find the height, then you can find the volume.

The surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².

Volume of cones the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

Volume of cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

The height of the cone is 6.5 cm and the radius is 2.5 cm. Put the values in the above formula,

[tex]V=\dfrac{1}{3}\pi r^2h\\V=\dfrac{1}{3}\pi (2.5)^2(6.5)\\V=\dfrac{1}{3}\pi (6.25)^2(6.5)\\V=\dfrac{40.625\pi }{3}\\V\approx42.5\rm\;cm^3[/tex]

The surface area of cone can be find out by the following formula,

[tex]A=\pi r(r+\sqrt{h^2+r^2})[/tex]

Again put the values in this formula,

[tex]A=\pi \times2.5(2.5+\sqrt{(6.5)^2+(2.5)^2})\\A=\pi \times2.5(2.5+\sqrt{48.5})\\A=\pi \times2.5(2.5+6.96)\\A=\pi \times2.5(9.46)\\A=74.33\rm\; cm^2[/tex]

Thus, the surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².

Answer:

25 ≤ 2.5n

Step-by-step explanation:

Total budgeted amount = $25

Cost per pack of = $2.50

To represent the relationship using inequality :

Let the Total number of packs purchased = n

Hence,

Total budgeted amount ≤ (cost per pack * number of packs)

25 ≤ 2.5n

This means the total actual purchase made should be less than or equal to the budgeted amount.

Answer:

21.45

Step-by-step explanation:

Answer:

Ron needs $21.45 more

Step-by-step explanation:

soccer ball price + pair of shorts price + pair of soccer shoes price = total amount needed

11.15+ 13.30 + 7.60 = 32.05

Ron has 10.60

32.05-10.60=21.45

Thanks in Advance For Brainiest

Step-by-step explanation:

First, we want to find the area of the circle at the top of the cylinder, so we want to do πr^2 so 3.14x(11.4/2)^2

This is = to 102.0186

Then we do 102.0186 times the height or 10.7 to get 1091.59902

We simplify to get 1091.6

Step-by-step explanation:

A Dilation is defined as  a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the  dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1,  the image obtained after the  dilation is smaller than the pre-image and it is an "Reduction".

In this case you know that the triangle ABC was dilated by this scale factor:

With the origin as the center of dilation.

Since:

It is a Reduction.

You can identify that the vertices of the triangle ABC are:

So you need to multiply the coordinates of each vertex  of the triangle ABC by , in order to get the coordinates of the triangle A'B'C. Then, you get:

Step-by-step explanation:

Answer:

m∡B = 55°

AB = 5.2

AC = 7.4

Step-by-step explanation:

m∡B = 180-(90+35)

use Law of Sines to find AB and AC:

sin 90° / 9 = sin 35°/AB

AB = .57(9) = 5.2

sin 90° / 9 = sin 55°/AC

AC = .82(9) = 7.4

The solution is,

m∡B = 55°

AB = 5.2

AC = 7.4

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

from the given figure, we get,

m∡B = 180-(90+35)

        =55

use Law of Sines to find AB and AC:

sin 90° / 9

= sin 35°/AB

AB = .57(9)

     = 5.2

sin 90° / 9 = sin 55°/AC

AC = .82(9

     = 7.4.
