So you will need to find the height, and we can do so by using the pythagorean theorem, which is 
. Using this formula, we can make the equation 
Firstly, solve the exponents: 
Next, subtract 225 on both sides: 
Lastly, square root both sides, and your answer is h = 20.
Now that we got the height, we can solve for the volume, which is 
. Using this formula, we can form our equation to be 
Firstly, solve the exponent: 
Next, multiply 225 and 20/3, and your answer will be V = 1500π, or the third option.
Step-by-step answer:
If there are 40% students that are girls , and the rest are 250 boys. Then that must mean there are 60% boys. Because that is the compliment.
i)
Because we know that 60% of the people in the group are boys, and that the amount of boys amounts to 250, we can model an equation like this.
.
There are 417 students
ii)
Because we know that the total amount is 417, we can find the amount of girls there are by multiplying the total by the percentage.
There are 167 students that are girls.
To find x we are gonna use the cosine formula.
Cos 0 = adj/hyp
0 represents theta
Cos 0 = adj/hyp
Cos 0 = 25/40
Convert 25/40 to decimal from
25/40 = 0.625
On a scientific calculator press the key “2nd F” or “Shift” then “cos”(which would give cos inverse) then type 0.625 equal.
Cos-1 0 0.625
= 51.31 degrees
x is therefore 51.3 degrees to the nearest tenth
