Answer:
6
Step-by-step explanation:
We know that the area of a circle is equal to 
.
A semi-circle is a half-circle, meaning that it will have half of the area of a full circle.
Therefore, a semi-circle's area is equivalent to 
.
Set this equation equal to 18.
Solve for r.
We then find that r = 6.
Now, we need to find the circumference. We know that the equation for the circumference of a circle is 2r. Since we only need the perimeter of half of a circle, our circumference equation will equal r.
Plug 6 in for r.
The perimeter of the garden is equal to 6.

when u read this and wish I had a bf. :(
Answer: B
Step-by-step explanation: To get the boys part of the ratio you will have to subtract 30 students and 14 students that are girls because all together there are 30 students and since we only know that 14 of them are girls that leaves the rest of the students boys. 30 - 14 = 16 so now we know how many boys there are. 16:14 can be reduced by 2 and that equals to 8:7.
Hope this helps!
<span>Since, there are 26 letters in total.</span>
So, total permutations of 26 letters in the 6 letter word will be = 26*26*26*26*26*26 = 26^6
No. of letters that doesn’t include X = 26-1 =25
Permutations of letters that doesn’t include x = 25*25*25*25*25*25 = 25^6
So, total number of permutations that includes x= total permutations of 26 letters- permutation of letters that doesn’t include x
= (26^6 - 25^6) = 64,775,151
