Question

Linda throws a dart that hits the square shown below:

A square is drawn. A circle of radius 9 units touches the sides of the square.

What is the probability that the dart hits a point in the circle?

Answer 1

We can assume the size of the square because the circle istouching the sides of it.

What is the area of the square?
What is the area of the circle?

Area of a square = side * side
Area of a circle = \(\pi\) * radius^2

Radius = diameter/2

The probability of hitting the circle inside the square is going to be the area of the circle over the area of the square.
