I'm going to suppose that this is asking for the volume.
The formula to find volume for a cylinder is V= pi r 2(squared) h
The radius is 10cm and the height is 14cm
Then plug the numbers in
So you should get V=3.14 x 10(squared) x 14
The once you multiply all that you should get 4396 cm(cubed)

Answer:

3√11

Step-by-step explanation:

You use the Pythagorean Therom, 18^2-15^2 give you 99. You find the square root of 99, you break it down into 9 and 11. Take the square root of 9, which is three, and you cant seperate 11. So thats how you get 3√11

Find a single expression that represents the area of the outer ring of the circle if the area of the whole circle is represented

sp2606 [1]

Answer: The answer is $A_o=2\pi\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Step-by-step explanation: Given that the area of the whole circle is represented by the expression

$A_c=25x^2-12x-9.$

We are to find the area of the outer ring of the circle, i.e., to find the circumference of the circle.

Now, if 'r' represents the radius of the circle, then we have

$A_c=\pi r^2\\\\\Rightarrow \dfrac{22}{7}r^2=25x^2-12x-9\\\\ \Rightarrow r^2=\dfrac{7}{22}(25x^2-12x-9)\\\\\Rightarrow r=\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Thus, the area of the outer ring is

$A_o=2\pi r=2\pi\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Anastaziya [24]

Answer:

Range: [1,25]

Step-by-step explanation:

You may find it easier to express the domain in set notation rather than in words: [1,9], or 1 ≤ x ≤ 9. The smallest value of f(x) = 3x - 2 is at x = 1 and is 3(1) - 2, or 1. The lasrgest value of f(x) is at x = 9 and is 3(9) - 2, or 25.

Thus, the range of this function is [1,25] or 1 ≤ y ≤ 25.
