Ah, a circle has 360 degrees in total, so if we take 90 degrees from that, we are looking at a quarter of the circle. Just imagine a slice of pie, one-fourth of the whole delicious pie. It's a lovely angle that can bring balance and harmony to your circle painting.
A single one of four equal parts is called a "quarter." In mathematical terms, when an object or a whole is divided into four equal parts, each part represents one-fourth or 1/4 of the whole. This concept is commonly used in fractions and is essential in various mathematical operations and measurements.
Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.
No,Circumference is like the perimiter and Area is the whole circle.
