Sandy wants to cover a wooden cylinder with a diameter of 1 ft and a height of 4 ft with carpet to build a scratching post for h

aleksley [76]

Answer:

Sandy needs $14.13\ ft^{2}$ of carpet to build a scratching post for her cats

Step-by-step explanation:

Sandy needs to calculate the surface area of the cylinder

The surface area of the cylinder is equal to

$SA=2\pi r^{2}+2\pi r(h)$

we have

$r=1/2=0.5\ ft$ ----> the radius is half the diameter

$h=4\ ft$

assume

$\pi =3.14$

substitute the values

$SA=2(3.14)(0.5)^{2}+2(3.14)(0.5)(4)$

$SA=14.13\ ft^{2}$

Sandy needs $14.13\ ft^{2}$ of carpet to build a scratching post for her cats

Answer:

I believe it is 48%

Step-by-step explanation:

The total amount of people who liked to read printed books is 67.

Then the total amount of people who liked either print or electronic books is 140.

If I am remembering correctly, you would divide 67 by 140 to get the percentage of people who like to read printed books.

<u>67/140 = 48%</u> (rounded)

The sum of two numbers is 24. The difference is 15. What are the two numbers?

tatiyna

The numbers are "x" and "y",
we suggest this system of equations.
x+y=24
x-y=15
solve by reduction method.
x+y=24
x-y=15
-----------------
2x=39 ⇒x=39/2=19.5

x+y=24
-(x-y=15)
-------------------
2y=9 ⇒y=9/2=4.5

The numbers are 19.5 and 4.5

To check
19.5+4.5=24
19.5-4.5=15
