What’s the area of the radius is 6?
A = πr2 , where r is the radius of the circle …. Thus, after rounding off the answer to one decimal point, the area of the circle is 113.1 ft2 (answer choice D).
What is the area of a 6 inch circle?
Answer: The area of a circle with a diameter of 6 units is 28.27 sq.
How do you find area?
Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn’t on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale).
What is the diameter of 5?

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.
