Hi there! :)
Answer:

Step-by-step explanation:
Formula for the area of a circle:

Rearrange the equation in terms of "r":
Divide 'π' from both sides:

Take the square root of both sides:

Answer: 0.444225
Step-by-step explanation:
Given : The total number of tickets = 50
Number of tickets are randomly sampled without replacement =6
Since the order of selection is not important , so we use combinations.
Total number of ways to select 6 tickets = 
The number of winning tickets = 6
So, number of tickets that are not winning = 50-6=44
Number of ways of selecting zero winning numbers= 
Now , the probability of holding a ticket that has zero winning numbers out of the 6 numbers selected for the winning ticket out of the 50 possible numbers would be 

Hence, the required probability = 0.444225
Answer:
(x + 1)² + (y + 5)² = 48
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 1, - 5) and r = 4
, so
(x - (- 1))² + (y - (- 5))² = (4
)², that is
(x + 1)² + (y + 5)² = 48 ← equation of circle
