50 words of praise for teachers^-^

Four times of spring breeze,
Several autumn rains washed the gap
Black hair and frost weave the sun and the moon,
The spring and Autumn period is written in chalk
The silk is not old in spring,
Candle tears turn to ashes, autumn is thicker
Three thousand orchards of peach and plum in spring,
Autumn is full of fruits
——Teacher, hard work
Who brings us into the spacious classroom,
Teach us rich knowledge?
It's you! Teacher!
With your hard sweat,
Nurtured the spring just broken seedlings
Who is it -- the naughty us
Educate to be considerate and helpful?
It's you! Teacher!
Your care is like a warm spring breeze
Warm our hearts
Who is it? We are young
Cultivate a mature and sensible youth?
It's you! Teacher!
Your protection makes us grow up healthily
Bear fruit in the golden autumn
You have worked hard, teacher!
People who work hard in the heat and cold
You have worked hard, teacher!
People who devote their youth to nothing
We pay high respect to you!
——You have worked hard, teacher!
I can only help here, teacher
Teacher, you are like the drizzle in spring,
It moistens the flowers and irrigates the earth,
And we are sucking the drizzle to grow
Teacher, you are like a breeze in autumn,
Blow yellow earth, call gold rice,
And we got the fruits of the harvest
Teacher - on the dark road of my life, you lit the brightest lamp for me;
Teacher - on my misty life road, you are my guide;
Teacher: in my bumpy life, you pointed out the direction for me to move forward;
Teacher - you give me a pair of powerful wings, let me roam in the world of knowledge!

I have only one burning heart,
With the pulse of the motherland beating together
No matter where I am,
You will always be the home of my heart
　　
My heart is crying, my blood is surging,
I just want to say to you:
Motherland, I love you!

"Bu operator. Yong Mei" wind and rain send the spring back, snow welcome the spring. It is already a cliff of ice, there are still beautiful flowers. Qiao also does not fight for spring, only the spring to report. When the flowers bloom, she laughs in the cluster

What is the formula for calculating the volume of a cone
How to calculate the volume of the frustum, please use r for the upper radius, R for the lower radius, h for the height of the frustum

V＝ (1/3)*π*h*(R^2 + Rr +r^2)

The square formula of circle

Circumference of circle = diameter × circumference (π)
The letters are:
C circle = π D
Area of circle = radius × radius × circumference (π)
The letters are:
S circle = π R & # 178;

The square formula of circle

R squared

The formula of circle, cylinder and circle? The calculation method of circle? How to find the diameter, radius, perimeter and area of circle? (cubic, square)?

1. Circumference of circle C = 2 π r = π D 2. Area of circle s = π R ^ 2; 3. Arc length of sector L = n π R / 180 s is bottom area, height h, Volume V: v = sh, side area of cylinder = circumference of bottom * height s side = CH (Note: C is π d)

Is the volume formula of a sphere the cube of diameter or the cube of radius

Sphere volume v = 4 π R & # 179 / 3
Where R is the radius of the ball

A formula for the volume of a sphere expressed by its diameter

One sixth π D cube

How to calculate the volume of a circle? Height 500, diameter 500 Ask for Write down the formula thank you
How to calculate the volume of a circle

Calculation formula of sphere volume v = 4 / 3 π R ^ 3
R ^ 3 is the third power of the radius of the sphere
500 △ 2 = 250 (unit)
According to this, the volume of the sphere is:
4 / 3 × 3.14 × 250 ^ 3 ≈ 65416666.66 (cubic unit)
