You should know that numbers are generally classified as real and imaginary. Under the real numbers, they are further classified into rational and irrational numbers. Under rational numbers, these include fractions and integers. Irrational numbers are in decimal forms that cannot be converted to fractions. Therefore, the difference between the two is that: <span>-1.96312.. is a real, irrational number while </span>√(-5) is imaginary. There is no value for a root of a negative number.
X/12 = 9
x = 12 × 9
x = 108
If your answer is 2.34565 rounding to 2 decimal place will result in the answer being 2.35
anything 4 or below stays the same while anything 5 and above rounds up
Answer:
The depth of oil in the tin is 9cm
Step-by-step explanation:
The first thing we need to do here is to calculate the volume of the cylindrical tin.
Mathematically, that would be;
V = pi * r^2 * h
now, r = d/2 = 12/2 = 6cm
h = 14 cm
Thus the volume would be;
V = 22/7 * 14 * 6^2 = 1,584 cm^3
Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.
Now let’s say the height of the tin is x, this means its volume which is l * b * h = 16 * 11 * x = 176x
So the depth x would be;
176x = 1584
x = 1584/176 = 9 cm
