Describe radius in math
WebThe general equation of a circle is (x - a) 2 + (y - b) 2 = r 2, which represents a circle having the center (a, b) and the radius r. This equation of a circle is simplified to represent the equation of a unit circle. A unit circle is formed with its center at the point (0, 0), which is the origin of the coordinate axes. and a radius of 1 unit. WebWhich two terms can be used to describe AB? Solution: Radius; OA, OB, and OE ; PQ; Diameter and chord; Example 3: If a circle has a radius of 3 cm, what is the length of its longest chord? Solution: The longest chord is the diameter of the circle. Diameter = 2 × radius = 2 × 3 = 6 cm. Example 4: The minute hand of a circular clock is 21 cm long.

WebJan 2, 2024 · Figure 1.1. 1 shows the unit circle with a number line drawn tangent to the circle at the point ( 1, 0). We will “wrap” this number line around the unit circle. Unlike the number line, the length once around the unit circle is finite. (Remember that the formula for the circumference of a circle as 2 π r where r is the radius, so the length ... WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
