A piece of hard paper of right triangle with two right sides of 3 cm and 6 cm respectively. The volume of three-dimensional figure can be obtained by rotating one right side of it as an axis The maximum is () cubic centimeter?

A piece of hard paper of right triangle with two right sides of 3 cm and 6 cm respectively. The volume of three-dimensional figure can be obtained by rotating one right side of it as an axis The maximum is () cubic centimeter?


Taking the 3cm edge as the axis, the volume is 1 / 3 * π * 6 * 6 * 3 = 36 π cubic centimeter
Taking the edge of 6 cm as the axis, the volume is 1 / 3 * π * 3 * 3 * 6 = 18 π cubic cm
So the maximum is (36 π) cubic centimeters



If the three sides of a right triangle are 3cm 4cm 5cm, the length of the oblique side is? Cm


So many times of browsing, why no one answered. 5cm, the length of the hypotenuse is the side corresponding to the right angle, the longest one. In the future, you should think about this kind of question by yourself, don't always look for Baidu~~~··



The three sides of a right triangle are 3cm, 4cm and 5cm respectively. The area of this triangle is () square centimeter
A. 6B. 7.5C. 10D. 12


Triangle area: 4 × 3 △ 2 = 12 △ 2 = 6 (square centimeter); answer: the triangle area is 6 square centimeter



The three sides of a right triangle are 3cm, 4cm and 5cm respectively. Its area is () C ^, and its hypotenuse is
The three sides of a right triangle are 3cm and 4cm respectively
Cm, 5cm, its area is () cm2, its height on the hypotenuse is () cm, and the area of parallelogram with the same base and height is () cm2
