WebA semi-circle shaped rug has a diameter of 2 ft. What is the area of the rug? d = 2 ft; r = 1 ft; Area of circle = 3.14(1 ft (1 ft); Area of Circle = 3.14 ft 2; Area of semi-circle = 3.14 ft 2 ÷ 2; Area of semi-circle = 1.57 ft 2: 10: A spinner has 6 sectors, half of which are red and half of which are black. WebMar 24, 2024 · A circle is the set of points in a plane that are equidistant from a given point O. The distance r from the center is called the radius, and the point O is called the center. Twice the radius is known as the diameter d=2r. The angle a circle subtends from its center is a full angle, equal to 360 degrees or 2pi radians. A circle has the maximum possible …
Web**These two formulas are just two different ways of finding the same thing (circumference) because the diameter of a circle $$ =2 \cdot radius $$. So you can use whichever formula is more convenient. If you know a circle's radius, use the formula with radius ($$ 2 \cdot \pi \cdot radius $$) ; if you know the diameter, use the ($$ \pi \cdot diameter $$)
