Area= r*r*π (π ≈ 3.14)
⇒ Area= 4*4* π= 50.265
The area of the circle is 50.265~
Answer:
$3.4
Step-by-step explanation:
Total amount spent by Mila equals $71.05
She bought 5 yards of fabric at $12.85 per yard. Hence, the total amount she spent on fabric is 12.85 × 5 = $64.25
It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $71.05
Amount spent on thread = $71.05 - Amount spent on fabrics.
Amount spent on thread = $71.05 - $64.25 = $6.8
This is the total amount spent on thread.
But the question asks amount spent on one spool of thread. Since 2 spools would cost $6.8, one spool would cost $6.8 ÷ 2 = $3.4
4.25x + 7 = 53.75
Subtract 7 from both sides:
4.25x = 46.75
Divide both sides by 4.25:
X = 46.75 / 4.25
x = 11
