Introduction

In geometry, a rectangle is a four-sided shape with opposite sides of equal length and all internal angles are right angles. A circle is a set of points that are all equidistant from a central point called the center. In this article, we will explore the properties of a rectangle and a circle in relation to each other.

Rectangle Properties

A rectangle has several properties that make it a unique shape. The opposite sides of a rectangle are equal in length, and all internal angles are right angles. The perimeter of a rectangle is the total distance around the shape, which can be calculated by adding the lengths of all four sides.

Calculating the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, we need to know the lengths of all four sides. In this case, we are given that AB = 8 cm and BC = 6 cm. We can use the formula for the perimeter of a rectangle, which is:

Perimeter = 2(AB + BC)

Substituting the given values, we get:

Perimeter = 2(8 + 6) Perimeter = 2(14) Perimeter = 28 cm

Therefore, the perimeter of the rectangle is 28 cm.

Circle Properties

A circle has several properties that make it a unique shape. The center of a circle is the point from which all points on the circle are equidistant. The radius of a circle is the distance from the center to any point on the circle.

Calculating the Diameter of a Circle

To calculate the diameter of a circle, we need to know the radius of the circle. In this case, we are given that OC = 5 cm. The diameter of a circle is twice the radius, so we can calculate the diameter as follows:

Diameter = 2(OC) Diameter = 2(5) Diameter = 10 cm

Therefore, the length of the diameter of the circle is 10 cm.

Relationship Between Rectangle and Circle

In the given figure, we can see that the rectangle ABCD is inscribed in the circle with center O. The radius of the circle is OC, which is 5 cm. We can use the properties of the rectangle and the circle to find the length of the diameter of the circle.

Conclusion

In this article, we have explored the properties of a rectangle and a circle in relation to each other. We have calculated the perimeter of the rectangle and the length of the diameter of the circle. The perimeter of the rectangle is 28 cm, and the length of the diameter of the circle is 10 cm.

Introduction

In our previous article, we explored the properties of a rectangle and a circle in relation to each other. We calculated the perimeter of the rectangle and the length of the diameter of the circle. In this article, we will answer some frequently asked questions related to the properties of a rectangle and a circle.

Q&A

Q: What is the perimeter of a rectangle with opposite sides of length 8 cm and 6 cm?

A: The perimeter of a rectangle is the total distance around the shape, which can be calculated by adding the lengths of all four sides. In this case, we can use the formula for the perimeter of a rectangle, which is:

Perimeter = 2(AB + BC)

Substituting the given values, we get:

Perimeter = 2(8 + 6) Perimeter = 2(14) Perimeter = 28 cm

Therefore, the perimeter of the rectangle is 28 cm.

Q: What is the length of the diameter of a circle with a radius of 5 cm?

A: The diameter of a circle is twice the radius, so we can calculate the diameter as follows:

Diameter = 2(OC) Diameter = 2(5) Diameter = 10 cm

Therefore, the length of the diameter of the circle is 10 cm.

Q: What is the relationship between the rectangle and the circle in the given figure?
