You have to find out the radius of the circle so u have to find it in the middle of the circle
Well, zero is between negative and positive numbers. Negative number are less than zero and positive numbers. Positive number are greater than negative number and zero. And, zero is greater than negative number but smaller than positive number.
Negative number < Zero < Positive number
Write that as 7x. Writing it as x7 could lead to confusion. 7*x would be OK.
Mma can see that 2.09 is closer to 2 than 2.36.
The answer will be 388.6 because you will use the formula V=pi.r^2.h.
pi we know is 3.14 we also know that radius is half the diameter so half of 5 is 2.5 and the height is 9 so here is what we have so far. V=3.14x2.5^2x9.
2.5x2.5=13.75 13.75x3.14=43.175 43.175x9=388.575 and if we round that it will be 388.6 so your answer is 388.6
