First lets start by making the denominators the same. I multiplied the 4 by 5 and 10 by 2.

-25/20 = x -14/20
Add 14/20 on both sides (do the opposite to cancel out and whatever you do to one side you need to do to the other.
You should get -11/20 = x

Cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 5 inches. The height of the cone is 15 inche
ss7ja [257]

Answer:

V_{cylinder}=251.2\ in^3,

V_{cone}=251.2\ in^3,

V_{cylinder}=V_{cone}.

Step-by-step explanation:

The volume of the cylinder is

V_{cylinder}=\pi r^2 h,

where r is the radius of a base circle and h is the cylinder's height.

If cylinder has diameter of 8 inches, then its radius is 4 inches. The height of the cylinder is 5 inches. Thus, the volume of the cylinder is

V_{cylinder}=3.14\cdot 4^2\cdot 5=251.2\ in^3.

The volume of the cone is

V_{cone}=\dfrac{1}{3}\pi r^2 h,

where r is the radius of a base circle and h is the cone's height.

If cone has diameter of 8 inches, then its radius is 4 inches. The height of the cone is 15 inches. Thus, the volume of the cone is

V_{cylinder}=\dfrac{1}{3}\cdot 3.14\cdot 4^2\cdot 15=251.2\ in^3.

As you can see the cylinder and the cone have the same volume.

SpyIntel [72]

Answer:

The new area is 1800feet^2

Step-by-step explanation:

Step one:

Given data

The length and width or a rectangular courtyard is 40 feet and 30 feet

we can calculate the area of the courtyard as

Area= 40*30

Area= 1200 feet^2

when the extra 15 feet is added to the width

the new width is= 30+15= 45feet

The new area is

Area= 40*45

Area= 1800 feet^2

in all the area will increase by 1800-1200= 600feet
