Answer: The area of the circle with a radius of 4 units is 16π sq. units.

**Is a chord sometimes a radius?**

Radius: A circle’s radius — the distance from its center to a point on the circle — tells you the circle’s size. In addition to being a measure of distance, a radius is also a segment that goes from a circle’s center to a point on the circle. Chord: A segment that connects two points on a circle is called a chord.

**What is the area of a 5 inch circle?**

What is the area of a circle with a DIAMETER of 5 inches (radius of 2.5 inches)? How big is a 5 inch circle? The area of a circle is pi times the square of its radius. The radius is half the diameter. The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius.

## How to calculate the area of a circle?

Area = π * (Diameter / 2)2 Diameter of a Circle The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius.

## Which is half the radius of a circle?

The radius is half the diameter or r = d 2. The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2·r.

**How to calculate the radius of a sphere?**

Sphere surface area to radius calculator; User Guide. This tool will calculate the radius of a circle from the area, and will convert different measurement units for area and radius. Formula.
