Answer:
radius = 5.75 units
circumference = 36.11 units
Area = 103.81625 square units
Step-by-step explanation:
Radius = 11.5 / 2 = 5.75
Circumference = 11.5 x 3.14 = 36.11
Area = 5.75 x 5.75 x 3.14 =
33.0625 x 3.14 =
103.81625 units square
This is all if pi = 3.14

Answer:
Courtney is bringing 8 snacks
Step-by-step explanation:
Chelsea's snacks are represented as 2x.
2x means <u>2 · (a number)</u>
If Chelsea brought <u>16 snacks</u> and the <u>amount of snacks represented by 2x</u>, we have to figure out <u>what times 2 equals 16.</u>
In order to find out, we have to <u>divide</u>.
16 ÷ 8 = 2
This means 2 · 8 = 16
Since the amount of snacks Courtney brings is represented as <u>"x"</u>, she would have brought 8 snacks.
Hope this helped! :)
