Answer:
The total population of the school is 300 students.
Step-by-step explanation:
Considering, we are working with percentage we can use the equation:
y = %x.
To fill in the equation you can use what you already know, 60% = 180
180 = 0.60x
To solve this, you can then divide both sides of the equation by 0.60. This will then give you your answer, 300 = x.
For checking, you can do 180 = 0.60(300) which will result in 180 = 180.

Answer:
A
Step-by-step explanation:
The distance from the centre to a point on the circle is the radius.
Calculate radius r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (5, - 2)
r = 
= 
= 
= 8 → A
