The radius for number 2 is 9 inches the height is 20 inches. So you plug in those numbers into the equation to make: pi x 9^2 x 20 = 5089.38
The radius for number 3 is 10 inches and the height is 3 inches. So you plug in those numbers into the equation to make: pi x 10^2 x 3 = 942.48
The radius for number 4 is 5 inches and the height is 8 inches. So you plug in those numbers into the equation to make: pi x 5^2x 8 = 628.32
The radius for number 5 is 2 centimeters and the height is 5 centimeters. So you plug in those numbers into the equation to make: pi x 2^2(5) = 62.83
The answer is 2 because it’s the same length as the one labeled 2
the answer would be C because 7(-1) -5(-7) would be -7+35 which equals 28
The answer is #1, #2, and #4
It’s #1 because if you look at a number line -3 is before -4
It’s #2 because it’s less then or equal to and -4 is equal to -4
And lastly it’s #4 because 3 is greater then -4
Hope this helps!!
