5X10 = 50
102-50= 52
Answer = 52
Volume=hpir^2
d/2=r, 24/2=12=r
h=40
v=40pi12²
v=40pi144
v=5760pi cubic inches per section
Answer: D 1 and 5/72 sq ft
30 minutes
Because it would take her an hour to go 8 miles and she is only going 4 so it is half an hour
Answer: D) No; If x is 5, the expression on the left simplifies to 8, making the inequality false.
In other words, if x = 5, then x+3 becomes 5+3 which ultimately becomes 8, but this is not greater than 8 on the right side.
Your steps could look like this
x+3 > 8
5+3 > 8 ... replace x with 5
8 > 8 ... this is a false inequality
