How do you find the area of a shaded 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.

How do you find the area of a triangle in a rectangle?

A diagonal of a rectangle separates the rectangle into two congruent triangles. The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

What is the area of the shaded rectangle?

The area of the shaded region is the difference between the areas of the rectangle and the square. The dimensions of the rectangle are 6 by 8 and so the area is 6 times 8 , that is 48 square units. Each side of the square measures 2 units and so the area is 2 times 2 , that is 4 square units.

How many triangles are in a rectangle?

four isosceles triangles
Rectangle. A rectangle has opposite sides which are equal and parallel. It also has four right angles. The diagonals are equal and split a rectangle into four isosceles triangles.

What is circle and its formula?

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2, where ( h, k ) is the center and r is the radius.

Is a rectangle a circle and a triangle on a plane?

A rectangle, a circle and a triangle are drawn on a plane. What is the maximum possible number of points of intersection? The sides of the triangle are not collinear with any of the sides of the rectangle.

What is the radius of the largest circle cut out?

The largest square that can be cut-out of a circle of radius 10 cm will have its diagonal equal to the diameter of the circle. What is the radius of the largest circle that can be cut-out of the rectangle measuring 10 cm in length and 8 cm in breadth? The area of a square is 100 cm 2. The circumference (in cm) of the largest circle cut of it is

Are the sides of the triangle collinear with the rectangle?

The sides of the triangle are not collinear with any of the sides of the rectangle. Here is a proof that the answer by @Avi is the largest possible. Lemma: Let l be a straight line on the plane R 2 and X be a closed convex subset of R 2.

What is the area of a circle if the radius is tripled?

(a) Let r be the radius of a circle. If radius is tripled, then new radius will be 3r. Hence, the area of a cirlce becomes 9 times to the original area. In questions 38 to 56, fill in the blanks to make the statements true. Perimeter of regular polygon = Length of one side x Number of sides.
