Answer: the answer should be 7
Step-by-step explanation: V=πr2h
3=π·1.52·3
3≈7.06858
you can find the radius for the area of the base 7 by dividing by
like such 7/3.1459 the squared because remember its in r2 form which give you 1.5 then plug this in for one of two ways to solve A·
1/3 or V=πr2h
8. 3x-4>38
3x>38+4
3x>42
x>42/3
x>14
So the answer is A. x>14
9. It's A. Two less than four times a number is 12. Because 4x (four times) and also it says 2 less than 4 times a number...
