We know that circumference = diameter * 3.14, so in order to find the diameter all we have to do is:

circumference/3.14 = diameter

So, we can plug in the value of the circumference:

34 / 3.14 = 10.82

The exact answer is 10.82.

The approximate answer is 11.

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

I will gove brainlist ..The line graph shows the amount of water loss in a leaking tank during 7 hours.The owner pays $1for ever

kramer

Answer:

The owner will have to pay $ 125 after 2 hours.

Step-by-step explanation:

Given that the line graph shows the amount of water loss in a leaking tank during 7 hours, and the owner pays $ 1 for every 8 liters of water lost, to determine how much will he have to pay after 2 hours the following calculation must be performed :

((6000 - 5000) / 8) x 1 = X

(1000/8) x 1 = X

125 x 1 = X

125 = X

Therefore, the owner will have to pay $ 125 after 2 hours.
