Answer:
the big tank can hold 2027.37 m³of water
10 small tanks can be filled
Step-by-step explanation:
r = 11, h = 16
V = (1/3)πr²h
V = (1/3)121π(16)
1936π/3 = 2027.37
2027.37/200 = 10. 136
10 tanks
Answer:
$12.90
Step-by-step explanation:
To solve, multiply the cost before tax with tax, and then add the number gotten to the original amount.

Answer:
River D - 2580 miles
River C - 2980 miles
Step-by-step explanation:
Let the length of River D be represented with x
length of river C = 400 + x
total length of both rivers = 5560
x + 400 + x = 5560
2x + 400 = 5560
collect like terms
2x = 5560 - 400
2x = 5160
divide both sides of the equation by 2
x = 5160 / 2
x = 2580
length of river c = 400 + 2580 = 2980
