Answer:
r = 31.85 in or 100/π
Step-by-step explanation:
area = πd
200 = 3.14d
d = 63.69
r = 1/2d
r = 31.85 in

Answer:
2
x
Step-by-step explanation:
The diagonal divides the square into 2 right angles with legs s and hypotenuse x
Using Pythagoras' identity on one of the right triangles, then
s² + s² = x²
2s² = x² ( divide both sides by 2 )
s² =
( take the square root of both sides )
s =
= 
Thus
perimeter = 4s = 4 ×
= 
Multiply numerator/ denominator by 
perimeter =
= 2
x
Answer:

Step-by-step explanation:

x=tan^-1(
)
It has to be in Quadrant 1
or 3
for positive.

Unless that incorrect due to tan(x) range is
. Then the only answer is 
Answer:
85n >/= 1,045
Step-by-step explanation:
85 people times n buses has to equal or exceed 1,045 people
85n is greater than or equal to 1,045
85n >/= 1, 045
n >/= 12.29
So, since n has to be greater than or equal to 12.29, and there is no 29/100ths of a bus, they would need 13 buses (in case there's a follow-up question)
