Let's check each option
Option A
The percentage of people choosing winter as their favorite season is
which equals to
%
The percentage of the other seasons are
Autumn = 24%
Spring = 16%
Summer = 40%
Option A is incorrect
---------------------------------------------------------------------------------------------------------
Option B
Out of the summer season, there are 24% female and 16% male
Option B is correct
------------------------------------------------------------------------------------------------------------
Option C
As explained for option A, the percentage of people who choose Autumn is 24% which isn't the smallest percentage.
Option C is incorrect
-------------------------------------------------------------------------------------------------------------
Option D
There's 14% males and 10% female who choose Autumn as their favorite season.
Option D is incorrect since there's more male than the female who choose Autumn.
Answer: Option B
The formula to calculate circumference is πd or 2πr. We also know that 2r = d.
So, using these formulas, let's try to figure out the first row of the table.
The diameter is 14.
We know that 2r = d or 2r = 14, therefore r=7. This means the radius is 7.
The circumference is πd or 14π or ≈ 43.96.
Let's move to the second row.
We know that the radius is 21.
2r = d
2(21) = d
d = 42
The diameter is 42.
Therefore, the circumference is 42π or ≈ 131.88
Let's move to the final row.
We know that the radius is 10.5.
2r = d
2(10.5) = d
d=21
Therefore, the diameter is 21 cm.
Circumference = πd = 21π or ≈ 65.94
you have to solve it backward
51-6=45
45/(9/10)=50
