Answer:
x=15
Step-by-step explanation:
2/3x = 10
To find x divide both sides by 2/3.
2/3x÷2/3 = 10÷2/3
x=15
Answer: The value of x is 6.
Step-by-step explanation:
In the figure we have two secants.
A secant is a line that intersects a circle in exactly two points.
For the figure attached below:
![a\times b=c\times d](https://tex.z-dn.net/?f=a%5Ctimes%20b%3Dc%5Ctimes%20d)
So for the given figure,
![x\times 8=4\times (4+8)\\\\\Rightarrow\ x=\dfrac{4\times12}{8}\\\\\Rightarrow\ x=6](https://tex.z-dn.net/?f=x%5Ctimes%208%3D4%5Ctimes%20%284%2B8%29%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac%7B4%5Ctimes12%7D%7B8%7D%5C%5C%5C%5C%5CRightarrow%5C%20x%3D6)
Hence, The value of x is 6.
Volume of a cylinder = πr²h
where,
r is the radius of the cylinder
h is the height of the cylinder
Area of the rectangle = length X breadth
We can consider that a rectangle if rotated will form a cylinder.
In that case, the breath of the rectangle will become the diameter of the cylinder and the length will become the height of the cylinder.
