The radius of a circle is always half of the diameter of the circle. In this case, the diameter is 4, meaning that when we halve 4, we will get our radius. Therefore, the radius of the circle is \boxed{2}. Hope this has helped you understand and have a great day!

Hi,

x + y = 350                    (equation 1)

3x + 2y = 950                 (equation 2)


Use Substitution Method

Isolate variable x in equation 1


x = 350 – y                     (equation 3)


Substitute equation 3 into equation 2


3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100


Substitute y = 100 into equation 1


x + 100 = 350

x = 250


Answer: 250 $3 tickets and 100 $2 tickets were sold.
