例文
話し言葉 Is a circle a solid? No, it's flat. A sphere is a solid, because it takes up space. 円は立体かな? いや、平らだよね。球は空間の中で場所をとるから立体。
書き言葉・答案 A solid consists of a cylinder with radius 3 cm and height 5 cm topped by a cone with the same radius and a height of 4 cm. Find the volume of the solid in terms of π. 半径 3 cm、高さ 5 cm の円柱の上に、同じ底面で高さ 4 cm の円錐を重ねた立体がある。この立体の体積を求めよ。ただし、円周率は π とする。
