A building is in the shape of a regular octagon. Given that the vertices of the octagon lie on the circle , what is the area of the building to the nearest square unit?
The figure below represents a vertical cross-section of a tunnel, where the equation of its circle is , and is the diameter of the circle. If the unit length of the coordinate system is 54 cm, determine the inner height of the tunnel.
A radar is located at the point covering a circular region with a radius of 27 length units. Determine the equation of the circle that gives the boundary of the radar’s reach.
A radar is located at the point covering a circular region with a radius of 27 length units. Can the radar observe a ship at the point ?
In Owen’s backyard, a sprinkler sprays water over a circular area with a diameter of 6 feet. If Owen’s house is located at the origin, and his sprinkler is located 25 feet north of his house, determine the equation that represents the circle of the area sprayed with water.
