Hello!

The standard equation of a circle is x² + y² = r², when the center is at the origin.

So therefore, we just need to substitute the radius into the equation to find the appropriate equation.

x² + y² = (3)²

x² + y² = 9

Therefore, the equation of the circle is C, x² + y² = 9.

Given n(A) = 1300, n(A U B) = 2290, and n(A n B) = 360, find n(B).

Stels [109]

Answer:

n(B) = 1350

Step-by-step explanation:

Using Venn sets, we have that:

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

Three values are given in the exercise.

The other is n(B), which we have to find. So

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

$2290 = 1300 + n(B) - 360$

$940 + n(B) = 2290$

$n(B) = 2290 - 940 = 1350$

n(B) = 1350
