Radius

The radius is a line segment extending from the center of a circle or sphere to any point on its circumference or surface. It also refers to the distance of that line segment. The term is fundamental in geometry and is used to calculate a variety of properties, including area, volume, and circumference. It is a key concept in understanding the shape and size of circular and spherical objects. Furthermore, the radius can also describe the range or scope of something.

Radius meaning with examples

• The architect calculated the radius of the rotunda to determine the amount of materials needed for its curved roof. Accurate measurement of the radius was crucial for structural integrity and aesthetic appeal. The blueprint clearly indicated the radius ensuring precision during construction. The radius of the roof's curve greatly affected the amount of daylight that filtered through.
• To find the area of the pizza, the delivery driver first measured the radius from the center to the edge. They then used this measurement to determine the number of slices. Calculating the pizza's area allows the driver to price the pie accurately. A longer radius generally meant more slices and a greater surface area to enjoy. The pizza's radius determines how many people can eat from it.
• The military established a 50-mile radius around the base for security reasons. This radius defined the area of restricted access for the public. Civilians were not allowed to come inside the set radius. The radius determined the perimeter of the area which was patrolled. The size of this radius was determined by the number of soldiers available.
• When studying a planet, scientists determined the radius to calculate its volume. Precise knowledge of the radius allowed for accurate estimations of the planet's gravitational pull. The radius affects the weight of objects on the planet. This knowledge contributes to understanding the planet's composition and its capacity to sustain life. The planet's radius affects space exploration planning.
