How do you find the area of a curve?

The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a & x = b, integrate y = f(x) between the limits of a and b. This area can be calculated using integration with given limits.

How do I calculate the square footage of a curved driveway?

Calculate the square footage of the circle by first multiplying the radius by itself. Multiply the result by pi, or 3.14. The result of this calculation is in square inches. Convert this to square feet by dividing the result by 144.

How do you calculate square feet on a graph?

Length (in feet) x width (in feet) = area in sq. ft.

How do you measure a curved shape?

You’ll need a tool called a protractor and some basic information. You must also know the diameter of the circle. Then, you can apply the following formula: length of an arc = diameter x 3.14 x the angle divided by 360.

How do you measure a gravel driveway?

Measure the length and width of your driveway in feet. Multiply the length by the width to get surface area and divide the result by three because 4 inches is 1/3 of a foot. You now have the volume of gravel needed in cubic feet. Divide the volume in cubic feet by 27 because there are 27 cubic feet in a cubic yard.

How do you calculate square footage with 4 sides?

Use the following equation: Area = side × side or A = s. Example: If one side of a square has a length of 4 feet, (t = 4), then the area of this square is simply t2, or 4 x 4 = 16 square feet….Parallelograms include:

1. Squares: Four sides, all the same length.
2. Rectangles: Four sides; opposite sides have same lengths.

How big is each square on graph paper?

Graph paper, which is paper covered in a square grid, makes it easy to maintain scale; you simply assign each square a specific size, such as 1 square foot, which means each side of the square equals 1 foot.
