A sphere is inscribed in a cylinder. Use complete sentences and geometric formulas to compare the surface area of the sphere and
Papessa [141]

Answer:

1 : 1

Step-by-step explanation:

When a circle is inscribed in a cylinder, the height of the cylinder is equal to the diameter of the sphere and the radius of the cylinder is same as that of the sphere.

Let the radius of sphere is r.

height of cylinder, h = 2r

radius of cylinder = r

Surface area of sphere, A = 4πr²

lateral surface area of cylinder, A' = 2 πrh

A' = 2πr x 2r = 4πr²

The ratio of surface area of sphere to the lateral surface area of cylinder is 1 : 1.

A closed can, in a shape of a circular, is to contain 500cm^3 of liquid when full. The cylinder, radius r cm and height h cm, is
Gemiola [76]
To express the height as a function of the volume and the radius, we are going to use the volume formula for a cylinder: V= \pi r^2h
where
V is the volume 
r is the radius 
h is the height 

We know for our problem that the cylindrical can is to contain 500cm^3 when full, so the volume of our cylinder is 500cm^3. In other words: V=500cm^3. We also know that the radius is r cm and height is h cm, so r=rcm and h=hcm. Lets replace the values in our formula:
V= \pi r^2h
500cm^3= \pi (rcm^2)(hcm)
500cm^3=h \pi r^2cm^3
h= \frac{500cm^3}{ \pi r^2cm^3}
h= \frac{500}{ \pi r^2}

Next, we are going to use the formula for the area of a cylinder: A=2 \pi rh+2 \pi r^2
where
A is the area 
r is the radius 
h is the height

We know from our previous calculation that h= \frac{500}{ \pi r^2}, so lets replace that value in our area formula:
A=2 \pi rh+2 \pi r^2
A=2 \pi r(\frac{500}{ \pi r^2})+2 \pi r^2
A= \frac{1000}{r} +2 \pi r^2
By the commutative property of addition, we can conclude that:
A=2 \pi r^2+\frac{1000}{r}

Sam has twice as many books as Jim. If Sam gives 12 books to Jim, they will have the same number of books. How many books do the
Neko [114]

Alright, lets get started.

Suppose number of books Jim have = x

Sam has twice as many books as Jim. So,

Number of books Sam have = 2x

If Sam gives 12 books to Jim, they will have the same number of books.

When Sam gives 12 books, his remaining books will be = 2x - 12

When Jim gets 12 books from Sam, his books will be = x + 12

And as per given question, they both now have equal books, so

2x - 12 = x + 12

Adding 12 in both sides

2x - 12 + 12 = x + 12 + 12

2x = x + 24

Subtracting x from both sides

2x - x = x + 24 - x

x = 24

It means Jim has number of books = 24

So, Sam has numberof books = 24 * 2 = 48

So, they have number of books together = 24 + 48 = 72 : Answer

Hope it will help :)

9x+18+3x=1
Katen [24]
The error is in the second step they subtracted 3 from both sides but it was a 3x, which you can not do.
Correction.
9x+18+3x=1
12x+18=1
12x=-17
x=-17/12
