技術說明

本發明提供一種圓面積量測工具，包括一圓筒，其上設有一第一開口，圓筒內可裝設一液體；一長方形容器，其上設有一第二開口，於長方形容器之至少一側面設有至少一刻度表；以及一導管，設於圓筒及長方形容器上，連接第一開口及第二開口，圓筒傾斜時，裝滿圓筒內之液體透過導管流入長方形容器中，依據長方形容器之一長度、一寬度、一高度及刻度表計算出液體在長方形容器中之一體積，該體積等於圓筒之內圓體積，再將內圓體積除以圓筒之高度，即可得到圓筒之一內圓面積。 The present invention provides a circular area measuring tool comprising a cylinder provided with a first opening in which a liquid can be provided; a rectangular container having a second opening on at least one side of the rectangular container And at least one scale is provided; and a conduit is arranged on the cylinder and the rectangular container to connect the first opening and the second opening. When the cylinder is tilted, the liquid filled in the cylinder flows into the rectangular container through the conduit, One of the length of the container, a width, a height, and a scale to calculate the volume of the liquid in the rectangular container, which is equal to the inner volume of the cylinder, and the inner circle is divided by the height of the cylinder to obtain a circle One of the inner circle area.
