How do you find the area of a cylander?
-- Slice it down one side and flatten it out. -- Now you have a rectangle. You only have to find the area of a rectangle. -- The area of a rectangle is (length) times (width). -- The length of the rectangle used to be the length of the cylinder. -- The width of the rectangle used to be the circumference of the cylinder's round ends, while it was still rolled up.
How do you find the length and width of a rectangle?
the length of a rectangle is 8 more than the width. the area os 345 centimeters. find the length and width of the rectangle
How do you find the width of a rectangle if you know its length and area?
Area of rectangle divided by its length = width of rectangle
How do you calculate the surface area of a cylinder?
OK. Let me give you an example.Lets suppose the radius of a cylinder is 3.5 ft, the Diameter is 7 ft and the height is 14 ft. find the surface area. Show all your work.In order to find the surface area you have to calculate all the areas. and then add them up.Area of a circle is Pi times the radius squared.Pi is 3.14Area of a circle is 3.14 X 3.5 ft2Area of a circle is 3.14 X 12.25 ftArea of a circle is 38.465 ft2Now a cylinder has two circles that equal each other, so all we have to do is multiply 38.465 ft2 X 2.Area of both circles is 76.93 ft2Second you have to find the area of the rectangle that is wrapped around the cylinder. When the rectangle is wrapped around the cylinder it creates a circumference which is the length of the rectangle.So we need to find the circumference.Circumference is Pi times the diameter.Pi is 3.14Circumference is 3.14 X DCircumference is 3.14 X 7 ftCircumference is 21.98Now that we know the Circumference we can find the area of the rectangle wrapped around the cylinder.Area of a rectangle is Length times the Width.(The height of a cylinder is also the width of the rectangle).Area of a rectangle is 21.97 X 14 ftArea of a rectangle is 307.72 ftOK. we calculated all the areas. BUT we still aren't done. We have to add all the areas up.76.93 ft2 + 307.72Surface Area is 384.65
How do you find area for cylinders?
First of all, find the area of the circle on top of the cylinder, using the formula... pi x radius^2 ... Multiply that by two because there are two circles on the cylinder. Then find the area of the rest of the cylinder, which is basically a rectangle. So, get the height, and multiply it by the circumference of the circle (also the length of one side of the rectangle) using the formula ... pi x diameter ...

The length of a rectangle is 5 more then the width Find the perimeter and the area of the rectangle?
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
How do you find length of rectangle?
You can measure it.
How do you find the width of a rectangle if you know its length and area?
Area of rectangle divided by its length = width of rectangle
How do you find the area of a square and a rectangle?
Multiply the length and width to find the area of both a rectangle and square.
How do you find ratio of two rectangles?
If you are trying to find the ratio of the lengths of two similar rectangles, divide the length of one side of one rectangle by the corresponding side length of the other rectangle. To find the ratio between their volumes, divide the volume of one rectangle by the volume the other rectangle. To find volume, multiply the width of the rectangle by the length of the rectangle.
The length of a rectangle is twice the width width the perimeter is 48 in find the dimensions of the rectangle?
If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.

How do you find the area of a rectangular base?
In order to find the area of a rectangle, multiply the length by the width of the rectangle. For example: If the length of a rectangle is 5cm and the width of a rectangle is 2cm, then the area of the rectangle would be 5cm X 2cm = 10cm².
