A cylinder with a circumference of 9.42 cm at the bottom is obliquely cut off from the middle. The cut shape is shown in the figure. What is the cut volume?

A cylinder with a circumference of 9.42 cm at the bottom is obliquely cut off from the middle. The cut shape is shown in the figure. What is the cut volume?

9.42 ﹣ 3.14 ﹣ 2 = 1.5 (CM) 3.14 × 1.52 × 4 + 3.14 × 1.52 × (6-4) ﹣ 2 = 28.26 + 7.065 = 35.325 (cm3). A: the cut volume is 35.325 cm3

A cylinder with a circumference of 18.84 cm at the bottom, cut a section obliquely from the middle, and the cut shape is as shown in the figure below. Calculate the cut volume

First, calculate the radius: 18.84 ／ 3.14 ／ 2, then divide it into two parts to calculate the first part: 3.14 × square of radius × 4, the second part: 6-4 = 2cm, 3.14 × square of radius × 2 ／ 2, and add up the last two parts
