Answer:
<h3>Area =Pi r2</h3>
=3.14×10x10
=3.14×100cm2
=3.14cm2
<h3>Perimeter = 2 pi r</h3>
=2 ×3.14×10
=6.28cm
Or =Pi d
= 3.14 ×20cm
=62.8cm
<h3>Note:</h3>
R means radius
D means diameter
radius is half of a diameter e.g radius is10 and diameter is 20

Answer:
-47b + 19
Step-by-step explanation:
<u>Answer:
</u>
The relationship between the two sets A and B if A ⊆ B is A is subset of B
<u>Solution:
</u>
A is subset of B means,” all elements of set A are present in set B”
Consider two sets A and B where
,
A = {1,2,3,4,5}
B = {1,2,3,4,5,6,7,8}
All Elements of set A {1,2,3,4,5} are present in set B
hence we relate set A and set B as A ⊆ B,which means set A is subset of set B. Symbol “⊆” is used to denote subset
So set A is subset of set B (A ⊆ B)

Red= 0.3
Blue=0.4
Green=0.2
Regular=0.1
Step-by-step explanation:
Answer:
40 drops
Approximately 0.166 %
Step-by-step explanation:
It would be easier to work the same units for volume
Since there are 1000 ml in a liter
Original water volume 1.2 L = 1.2 x 1000 = 1200 mLl
The final volume of the acid-water solution = 1.202 L = 1202 mL
So total volume of acid added = 1202-1200 = 2 mL
Each drop of acid is 0.05 mL
Number of drops added = 2/.05 = 40 drops
Percent of acid in acid solution = (Volume of acid added)/(Final volume) x 100 = (2/1202) ≈ 0.00166 x 100 ≈ 0.166 %
