the longest straight line that can be drawn to connect 2 points on the circumference of a circle whose radius is 9 inches is
The longest straight line that can be drawn to connect two points on the circumference of a circle is known as the diameter, which is equal to twice the radius. Therefore, in this case, the longest straight line would be 2 times the radius of 9 inches, which is equal to 18 inches.
The longest straight line that can be drawn to connect two points on the circumference of a circle is called the diameter. In this case, the radius of the circle is given as 9 inches.
The diameter of a circle is always twice the length of its radius. So, in this case, the diameter would be:
Diameter = 2 * Radius
Diameter = 2 * 9 inches
Diameter = 18 inches
Therefore, the longest straight line that can be drawn to connect two points on the circumference of a circle with a radius of 9 inches is 18 inches, which is equal to the diameter of the circle.
