472 to the nearest 100 is 500

The sand we need to fill the cylinders is equal to the total volume of the six cylindrical posts .
Given terms ( common for each cylinder ) :
- height (h) = 4 ft
- radius. (r) = 0.5 ft

Since volume of each cylinder is equal, so total volume of six cylindrical post :
_____________________________

The answer for this will be
2a(1-2a ²+3bc)
Answer:
Probability of finding girls given that only English students attend the subject =33/59
Step-by-step explanation:
Given that during English lesson, there is no other lesson ongoing. The probability of getting girls in that class only will be equivalent to 33/59 since we expect a total of 59 students out of which 33 will be girls. Similarly, in a Maths class given that only Maths students attend the class, probability of having a girl is 29/61 since out of all students, only 29 prefer Maths and the total class attendance is 61
Y = -5x + 28
will be parallel to your equation because it has the same coefficient but will also pass through (3, 13)
