Answer:
20. 300π m³
21. 457 1/3 π cm³
Step-by-step explanation:
20. r = 10 ÷ 2 = 5
V = 5² × 12 × π = 25 × 12π=300π m³
21. r = 14 ÷ 2 = 7

V = 457 1/3 π cm³
Answer:
Length: 11
Width: 2
Step-by-step explanation:
If length is x then width is x-9
That means:
26 = x+x+x-9+x-9 = 4x-18 which means:
44=4x x=11
Length=x = 11
Width = x-9 = 11-9 = 2
There are 18 nickels and 36 total coins
18:36 is your original proportion, but we can simplify.
Divide by 2
9:18
Divide by 9.
1:2 is your final answer.
A.) is correct.
The answer to this question is -1.41615
Use this to solve:
4/5 = 16/x
Since these are equivalent fractions;
you can divide 16 by 4
then multiply by 5
that should give you the original price of the bean bag chair!
