The Cole family owns an above-ground circular swimming pool that has walls made of aluminum.

Find the length (l) of aluminum surrounding the pool as shown if the radius is 15 feet.
(use π=3.14 )


Type your result in an empty box provided below rounded to the nearest tenth.

I = 94.2 ft

Step-by-step explanation:

The formula for circumference is

if the radius is 15 all you need to do is plug it in and solve

multiply 2 and 15

30

multiply 30 and pi

94.2

add units and you're done

(if you use the symbol for pi in the calculator it gives you 94.25 but it said to use 3.14 for pi. If you use the symbol pi it's way more than just 3.14)

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
