Answer:
4m
Step-by-step explanation:
We are looking for the circumference
We need to find the radius
r = d/2 = 1.2/2 = .6
C = 2*pi*r
C = 2*pi*(.6)
C = 1.2*pi
We can approximate pi by 3.14
C =1.2*3.14
C =3.768 m
To the nearest meter
C = 4m
4 feet
Because if she used 1 feet of ribbon for 3 bows you need to multiply by 4 to 1 foot and you will get 12 bows
4/3
Amount of acid = 14.9% of 331 mL solution
= 0.149×(331 mL)
= 49.3 mL acid
