Answer:
418.00 cm³
Step-by-step explanation:
The volume of a cylinder is given by πr²h (r being the radius and h being the height)
The radius is half of the diameter: 6.4/2 is 3.2.
The height shown here is 13.
Instead of pi, the question says to use 3.14 instead of pi.
Putting these all together, you get 3.14×(3.2)²×13.
This can be expanded to 3.14×10.24×13.
From there, multiplying it all together gives you 417.9968 cm³.
The problem says to the nearest hundredth, so you want to round it to 2 decimal places. Since the 6 is above 5, it gets rounded up, leaving you with 418.00 cm³.
Answer:
I DON'T
KNOW
Step-by-step explanation:
Answer:
We want to simplify:
(3 + 1/4)*(3/5)
The first step is to write the first term as a single rational number.
We know that:
3*1 = 3
and 4/4 = 1
then:
3*1 = 3*(4/4) = (3*4)/4 = 12/4
We do this because we want to have the same denominator in both numbers, so we can directly add them.
Then we get:
(3 + 1/4)*(3/5) = (12/4 + 1/4)*(3/5) = (13/4)*(3/5)
And remember that in the multiplication of rational numbers the numerator are multiplied together and the same for the denominators, then we get:
(13/4)*(3/5) = (13*3)/(4*5)
If we solve the multiplications we get:
(13*3)/(4*5) = (39/20)
Now, we can notice that in the numerator we have two prime numbers, 13 and 3.
And in the denominators, we have a 4 (which is equal to 2*2) and a 5.
So the prime numbers in the numerator and the denominator are all different, this means that we can not simplify it furthermore.
Then we have:
(3 + 1/4)*(3/5) = (39/20)
That answer I C. I hope this helps!!!!
Answer:
Step-by-step explanation:
y=x²+6x+5
=(x²+6x+(6/2)²)-(6/2)²+5
=(x+3)²-9+5
=(x+3)²-4
