How do you find the area of a rectangle and circle?

How do you find a rectangle in a circle?

Video quote: For relating these sides as L square length square plus width square equals to the diagonal is 2r. So we write this as 2 R square.

How do you find the area of a rectangular?

To find the area of a rectangle, multiply its width by its height. If we know two sides of the rectangle that are different lengths, then we have both the height and the width.

How do you find area with a circle?

The area of a circle is pi times the radius squared (A = π r²).

Can a rectangle be in a circle?

Actually – every rectangle can be inscribed in a (unique circle) so the key point is that the radius of the circle is R (I think). One of the properties of a rectangle is that the diagonals bisect in the ‘center’ of the rectangle, which will also be the center of the circumscribing circle.

How do you find the shaded area of a rectangle with a circle in it?

Calculate the area of both shapes. The area of a rectangle is determined by multiplying its length times its width. The area of a circle is Pi (i.e., 3.14) times the square of the radius. Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape.

How do you find the area of each shaded region?

Video quote: Again the radius is the distance from the center point of the circle to the edge of the circle.

What is the area of shaded portion?

Area of the shaded region = area of the square – area of the four unshaded small squares.

How do you find the area of the shaded region?

The Area of the shaded region = (Area of the largest circle) – (Area of the circle with radius 3) – (Area of the circle with radius 2). Whatever is left over is the shaded region.

How do you find the area of a circle in a square?

When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units. The area of a circle of radius r units is A=πr2 .

How do you find the shaded and unshaded region of a circle?

To get the area of the shaded region, subtract the area of the smaller circle from the area of the larger circle.
