1. Radius = 4 cm
2. Diameter = 8 cm
4 x 2 = 8
3. Circumference = 25.12 cm
8 x 3.14 = 25.12
4. Area = 50.24 cm^2
3.14 x 4^2
3.14 x 16 = 50.24
5. Radius = 5 in
6. Diameter = 10 in
5 x 2 = 10
7. Circumference = 31.4 in
10 x 3.14 = 31.4
8. Area = 78.5 in^2
3.14 x 5^2
3.14 x 25 = 78.5
9. Radius = 8 mm
16/2 = 8
10. Diameter = 16 mm
11. Circumference = 50.24 mm
16 x 3.14 = 50.24
12. Area = 200.96 mm^2
3.14 x 8^2
3.14 x 64 = 200.96
13. Radius = 7.4 cm
14.8/2 = 7.4
14. Diameter = 14.8 cm
15. Circumference = 46.472 cm
14.8 x 3.14 = 46.472
16. Area = 178.1636 cm^2
3.14 x 7.4^2
3.14 x 56.74 = 178.1636
17. Area = 44 m^2
10 - 6 = 4
8 x 4 = 32
6 x 2 = 12
32 + 12 = 44
18. Area = 7.74 mm^2
6 x 6 = 36
6/2 = 3
3.14 x 3^2
3.14 x 9 = 28.26
36 - 28.26 = 7.74
Just count the notches between the two points, there are 15 notches so 15 is tour answer
What is the following? but 8.4 x 102= 856.8 if that helps.
5^3 = 5*5*5 = 125
125 -12 = 113
113 / 3 = 37.6666666
I think I know how to do it
Your equation is:
P₁V₁ = P₂V₂
You Know:
Initial:
P₁ = 84 Pa
V₁ = 336 L
New:
P₂ = ?
V₂ = 216L
Plug this into the equation:
P₁V₁ = P₂V₂
(84 Pa)(336 L) = P₂(216 L) Divide 216 on both sides
130.6666666 = P₂
(if your doing significant figures, you have 2 sig figs)
130 Pa = P₂
