Acat scan produces equally spaced cross-sectional views of a human organ that provide information about the organ otherwise obtained only by surgery. suppose that a cat scan of a human liver shows cross-sections spaced 1.5 cm apart. the liver is 15 cm long and the cross-sectional areas, in square centimeters, are 0, 18, 59, 78, 95, 106, 118, 129, 62, 38, and 0. use the midpoint rule with n = 5 to estimate the volume v of the liver. v = cm3

1,107 cc

Step-by-step explanation:

The 10 intervals of the scanning are

[0,1.5), [1.5,3), [3,4.5), [4.5,6), [6,7.5), [7.5,9), [9,10.5), [10.5,12), [12,13.5), [13.5,15)

The ideal thing would be to estimate the volume with the Midpoint Rule should be take n=10.

As we must use n=5, we divide the interval [0,15] in five intervals of length 15/5 = 3

[0,3], [3,6], [6,9], [9,12], [12,15] and take their midpoints

1.5, 4.5, 7.5, 10.5, and 13.5.

Now we estimate the volume V of 5 cylinders of height h=3 and area of the base A equals to the area given for the scanning where that midpoints fall

Cylinder 1

Midpoint=1.5, interval of scanning 2nd

A = 18, V= height*area of the base = 18*3 =54  cc

Cylinder 2

Midpoint=4.5, interval of scanning 4th

A = 78, V= height*area of the base = 78*3 =234  cc

Cylinder 3

Midpoint=7.5, interval of scanning 6th

A = 106, V= height*area of the base = 106*3 =318  cc

Cylinder 4

Midpoint=10.5, interval of scanning 8th

A = 129, V= height*area of the base = 129*3 =387  cc

Cylinder 5

Midpoint=13.5, interval of scanning 10th

A = 38, V= height*area of the base = 38*3 =114  cc

And the estimate volume is

54+234+318+387+114=1,107
