We have the formula S= r * theta , where S is arc length , r is radius , and theta is central angle in radians
So AB= 4 * 45* π/180 = π units
9 I think because 1/4 needs to have 4 of those to be a whole so yeah 9.
You would need to find the circumference(using the formula c=3.14r^2) of the tree which is 113.04 then you would have to divide it by 6 which is 18.84 which would round up to 19
Answer: 19 people
Answer:
17 tour guides
Step-by-step explanation:
First, we need to divide 83 by 5.
As you can see, there are 16 tour guides that can handle 5 students each. However, there are a remainder of 3 students, so we need one extra tour guide. Thus, the answer is 17 tour guides.
We can use the difference of two squares, which is:
x^2 + y^2 = (x-y)(x+y)
So,
(9m-7)(9m+7)
Hope this helps!
