Answer:
The area of the circle is 50.24 mm
²
Step-by-step explanation:
To solve this exercise we need to use the area formula of a circle:
a = area
r = radius = 4mm
π = pi = 3.14
a = π * r²
a = 3.14 * (4mm
)²
a = 3.14 * 16mm
²
a = 50.24 mm
²
The area of the circle is 50.24 mm

Here you go. Just remember PEMDAS.
P-parentheses
E- exponents
M-multiplication
D-division
A-addition
S-subtraction
That is the order you will do it in.
The answer is 2. This is because 2 = 4% of 50.
You can think of it like this:
4 is 4% of 100.
50 is half of 100.
Therefore, 4% of 50 is HALF of 4% of 100.
4 divided by 2 = 2
2 one do you need explanation ??
Answer: The final answer to this question is 4:3
Step-by-step explanation:
The definition of a ratio is "the quantitative relation between two amounts showing the number of times one value contains or is contained within the other." In English, it's essentially how many "things" there are for every "other thing" there is. In this case, for every 8 girls there are, there are also 6 boys. There are many ways to write a ratio but the main one is with a colon.
So the ratio would be written like this 8:6
However, the statement requires it to be in simplest form so we need to simplify the ratio. We do that much like simplifying a fraction. Find the least common denominator, then divide both values by it. In this case the LCD is 2. So all we need to do now, is divide both the numbers in half, then we have our simplified ratio.
See :
8/2 = 4
6/2 = 3
So our new and final ratio is 4:3
Hope this helped you understand :)
