Given that the two right angles of a right triangle are 6 and 8 respectively, the distance from the intersection of the three interior bisectors to the right triangle is equal to ()

The bevel is 10,
This distance, which is the radius of the inscribed circle of the triangle, is set to R,
Triangle area,
S=6*8/2=24
On the other hand, the triangle is divided into three parts from the intersection point to the three vertices,
S=(6+8+10)r/2
So r = 2

The two right sides of a right triangle are 6 and 8 respectively. What is the length of the hypotenuse?

Rotate a right triangle with a side length of 6 cm 8 cm 10 cm around one of its right angles. What is the volume of the figure

1. If we take the right angle side of 6cm as the axis, we will produce a cone. The height of the cone is 6 cm. The radius of the bottom of the cone is 8 cm. The volume of the cone is 3.14x8x8x6 △ 3 = 401.92 (cubic centimeter). 2. If we rotate the right angle side with the side length of 8 cm as the axis, we will produce a cone

A triangle whose two right angles are 3cm and 4cm respectively. The volume of the three-dimensional figure is obtained by rotating the shorter right angle side as the axis______ cm3．

One
3×3.14×42×3，
=1
3×3.14×16×3，
=50.24（cm3）；
So the answer is: 50.24

When a right triangle with right angles 3 and 4 is rotated around the right angle side, the maximum volume of the solid figure is___ .

① For a cone with a radius of 3 and a height of 4:
S1=1
3×3.14×32×4，
=1
3×3.14×9×4，
=37.68；
② A cone with a base radius of 4 cm and a height of 3 cm:
S2=1
3×3.14×42×3，
=3.14×16，
=50.24；
The maximum volume is 50.24
So the answer is: 50.24

The volume of the solid figure is calculated by rotating the right triangle around the hypotenuse axis. The bottom edge is 3cm, the height is 4cm, and the hypotenuse is 5cm

3×4÷5=2.4(cm)
The square of π × 2.4 × 5 × 1 / 3 = 30.144 cubic centimeter
A: briefly
(Note: π = 3.14)

As shown in the figure, rotate around the hypotenuse of a right triangle, and what is the volume of the solid figure

The radius of the circle is r = AB / C
V=1/3×πr^2(h1+h2)=πr^2×c/3=πa^2×b^2/(3c)=πa^2×b^2÷(3a^2+3b^2)

Three sides of a right triangle are 3cm, 4cm and 5cm. Rotate the hypotenuse of the triangle for one cycle to calculate the volume of the solid figure (unit: cm) To understand

Make it high on the bevel
The plane where the height is located divides the solid figure into two cones
The height on the bevel is 3 * 4 / 5 = 12 / 5
The intersection of the height of the hypotenuse and the hypotenuse divides the hypotenuse into two parts
If one step is x, the other is 5-x
In this way, we can find the volume of two cones separately
The top one is 1 / 3 * (12 / 5) ^ 2 * π * X
Below is 1 / 3 * (12 / 5) ^ 2 * π * (5-x)
The two equations add up to make up the whole volume
1/3*(12/5)^2*π*x+1/3*(12/5)^2*π*(5-x)＝1/3*(12/5)^2*π*(x+5-x)
It's 1 / 3 * (12 / 5) ^ 2 * π * 5
So the integrated formula is like this
1 / 3 * (3 * 4 / 5) ^ 2 * π * 5 = 144 π / 15 (cubic centimeter)

In the following figure, one side of the right triangle with 4cm is the axis. Rotate it for a circle to get a cone. Calculate the volume of the cone. The height is 4cm, the slope is 5cm, and the bottom is 3cm Be careful. Don't be confused

The radius of the bottom of the cone is equal to the bottom edge of the right triangle, which is 3cm long and 4cm high,
According to the cone volume formula v = 1 / 3SH = 1 / 3 * 3.14 * 3 ^ 2 * 4 = 37.68 cubic centimeter

A rectangular triangle of cardboard is rotated around AB to form a cone. How many cubic centimeters is the volume of this cone?

One
3×3.14×52×9
=3.14×25×3
=3.14×75
=235.5 (cm3)
A: the volume of this cone is 235.5 cubic centimeters

Given that the two right angles of a right triangle are 6 and 8 respectively, the distance from the intersection of the three interior bisectors to the right triangle is equal to ()
