I think its 'cant be done'
Step-by-step explanation:
Answer:
1004.8 in³
Step-by-step explanation:
d = 2r => r = d/2 = 16in/2 = 8 inches
V = Ab×h
= π·r²×h
= 3.14·(8in)²×5in
= 1004
Answer:
The equation is;
d = 1.25s
Step-by-step explanation:
Here, we start by getting the price of a single song
From the question;
4 songs = $5
Thus, 1 song will be $5/4 = $1.25
So the proportionality constant is $1.25 per song
To write the relationship, we have;
d = 1.25s
Where d is the cost in dollars and s is the number of songs
