Answer: 1306.5 m^3

Step-by-step explanation:

1. The formula for the volume of a cylinder is: V=\pir^2h

2. If you substitute the values into the equation, you get

V = pi * 5.7^2 * 12.8 = 1306.5

3. 1306.5 is already to the nearest tenth, so that is the answer.

Jin has 1 and 3 tens, carla has 4 and 6 ones. what number can they make?
choli [55]
Jin has 1 and 3 tens.So that would be equals to
= 1 tens + 3 tens = 4 tens or 40.
Next, Carla has 4 and 6 ones. 
So that would be equals to
= 4 ones + 6 ones = 1 tens or 10.
Now, the question is, what number can they make together.
This simply means that if were going to add up the numbers that they both have, then how much will they make? 
=> 40 + 10 = 50 or 5 tens.
<span>Since, jin has a total of 4 tens and Carla has a total of 1 tens.</span>

Divide 33 photos into two groups so the ratio is 4 to 7
Advocard [28]
4 to 7
or
4+7= 12
4x+7x=33
x=3
so,
(4×3)+(7×3)=33
12+21=33
or
12 and 21.
hope it helped

Answer:

Step-by-step explanation:

Law of Sines  recall   Sin(A) /a  = Sin(B) /b  

does the above make sense?

Next we need to find  the angle of A

notice that 16+75=91  :o

so angle A is only 89° ..(b/c all the way around then inside of a triangle is 180)  so this is NOT a right triangle but that's okay, b/c law of sines still works fine.

then we want to find length of line AB

and if 89 = A  then a = BC

and if  75 = B the  b = AB (note that in the given triangle this is angle C, i'm using B , b/c you can see the difference between capital B and  lower case b much easier than you can with C, & c  :/   )

capitals are the angles while lower case are the length of the sides

then

Sin(89) / 29 = Sin(75) / b

solve the parts that can be put into numbers or solve for 'b' first, that means isolate 'b' all by itself on one side of the equal sign .

0.034477 = 0.965925/ b

b = 0.965925 / 0.034477

b = 28.0165

b = 28.0 ( to the nearest 10th)

we have the parts to plug in now

Sin(75) /
