Answer:
402 cm.
Step-by-step explanation:
To find this, we will need to calculate the circumference of the reel. We can do this using the formula 
.
Since the radius is 4 cm, the diameter is 8 cm. Put this into the equation to solve for the circumference:
Since the reel spun 16 times, simply multiply the circumference by 16 to get:
25.12 × 16 = 401.92
≈ 402 cm.

pres =6 and 3/4 times mec pay=17.25 times 6.75=116.4375, about $116.44
janitor is 3/4 or 0.75 of janitor=17.25 times 0.75=12.9375, about $12.94
add them
$17.25+$116.4275+$12.9375=146.615
round
$146.62

Answer:
to find Y
-4x + 11y = 15
x - 2y = 0
.
equal= -3x + 9y= 15
since x=2y
-3(2y) + 9y = 15
-6y + 9y =15
3y = 15
y = 15/ 3
y = 5
.
to find x
using x=2y
since
y=5
,therefore
x= 2(5)
x= 10
