Anonymous users2024-02-11Since it is a square, then the side length =
One side of the square is the circumference of the bottom circle, and according to the circumference area of the circle = 2 r=, you can approximate , so r=
then surface area = 2 r 2+. 2 means to the power of 2.

Anonymous users2024-02-10A square by circumference.
It can be seen that height = bottom circumference =
So the diameter is 1 and the radius is.
Surface area = 2 *r*r+

Anonymous users2024-02-09The perimeter is, so the side length is 1 4, so the radius of the upper and lower sides of the cylinder is, the surface area of the cylinder

Anonymous users2024-02-08The side length of the square is, then the height of the cylinder is, then the side area of the cylinder is, and then the area of the circle on both sides of the cylinder is calculated, and the circumference of the circle is. The circumference is 2 r, then the radius of the circle can also be found, and then the area is multiplied by r squared, then the surface area of the cylinder is the side area plus the area of the two circles.
I don't tell you the answer, I only tell you the method, I want you to be able to do this question thoroughly, hehe.

Anonymous users2024-02-07The side area of the cylinder = the height of the bottom perimeter.
The result is a square, indicating that the circumference and height of the bottom surface of this cylinder are equal.
The circumference of the bottom surface of the jujube type = diameter 2 8 2 = 16 (centi-rent) stool base.
The side area is equal to: 16 8 = 128 (square centimeters) look, thank you!

Anonymous users2024-02-05Summary. The side view of a cylinder is a square with a circumference of decimeters, what is the height of this cylinder? Body.
And this one.
Isn't this picture very clear, can you take it a little more clearly? Is it okay <>? It's okay, kiss, the answer has been sent over, please check<> thank you. What's wrong with the pro?

Anonymous users2024-02-03The circumference of the bottom surface of this cylinder is 10 cm, so the side length of this square is 10, so the height is 10, the side area is 100, the circumference is 10 cm (2 r=10), r = 5, the area is 25, and the volume is 250.
The height is (10cm);
The side area is (10cm*cm);
The volume is (250 cm*cm*cm).

Anonymous users2024-02-02The circumference of the bottom surface of the cylinder is equal to the height.
Height: 10 cm.
Side area: 10*10=100 square centimeters.
Bottom radius: 10 (2*cm.)
Volume: cubic centimeters.
