Find the height of a cylinder with radius 13 and surface area 1470.3.
g100num [7]
First you need the formula for SA of a cylinder: SA = 2(πr^2) + 2πr*h
(area of the top and bottom circles plus the side)
Then plug your values into the equation and rearrange to make h the subject:
1470.3 = 2π13^2 + 2π*13*h
26πh = 1470.3 - 338π
h = (1470.3 - 338π)/26π
   =5.00042...
so h is approximately 5 units :)

For which operations is the set {0, 1} closed?
velikii [3]
0 × <span>0 = 0
0 </span>× <span>1 = 0
1 </span>× <span>1 = 1

Which means multiplication is closed under {0, 1}

</span><span>1 </span>÷ <span>1 = 1
0 </span>÷ <span>1 = 0
</span>
Division is not closed under {0, 1}

1 + 1 = 2

Addition is not closed under {0, 1}

0 - 1 = -1

Subtraction is not closed under {0, 1} either



So it's only A. Multiplication which is closed under {0, 1}

two crates contain Apple's, pears and oranges. there are 184 apples and pears in crate one and 248 apples and oranges in the sec
Ray Of Light [21]

Answer: There are 152 apples.

The explanation is shown below:

- You need to write the following three equations, where a is the the number of apples, p is the number of pears and o is the number of oranges:

1) a+p=184

2) a+o=248

3) o=3p

-  You must substitute the equation 3) into the equation 2):

 a+3p=248

- Now, you need to solve for p in the equation 1) and then you must substitute it into a+3p=248:

p=184-a

a+3(184-a)=248

- Solve for a, as following:

a+552-3a=248\\-2a=-304\\a=\frac{-304}{-2}\\a=152

- Therefore, there are 152 apples.
