While the vertex, or standard form of the equation of a circle is expressed in this form: $$(x - h)^2 + (y - k)^2 = r^2 \\ $$ Answer and Explanation:1 We're asked to determine the center and radius of the circle whose equation is {eq}x^2 + y^2 + 4...
Each point on the circumference of a circle is equidistance from a fixed point called the center. And the distance from the center to the circumference is called the radius of the circle. The algebraic representation of the locus of a circle or the general equation ...
Answer to: Find the center and radius of the circle and write the standard form of the equation. By signing up, you'll get thousands of...
Move ( -16) to the right side of the equation by adding ( 16) to both sides.( ((x+6))^2+((y+4))^2=-36+36+16)Simplify ( -36+36+16).( ((x+6))^2+((y+4))^2=16)This is the form of a circle. Use this form to determine the center and radius of the c...
Determine the center and the radius ofthe circle that is defined by each of thefollowing equations. Then graph eachcircle on a coordinate plane (or useGeoGebra to graph each). Answer thequestions that follow.2. (x-5)^2+(y-6)^2=81 ...
“A circle is defined by its center and radius.” In this context, “radius” is different from ___. A. diameter B. circumference C. area D. volume 相关知识点: 试题来源: 解析 D。“radius”是半径。“diameter”是直径;“circumference”是周长;“area”是面积,都与圆相关。而“volume...
What is an equation of the circle whose center is (1,3) and whose radius is 2? A: (x + 1) + (y + 3) = 4 B: (x − 1) + (y − 3) = 2 C: x + y = 4 D: (x − 1) + (y − 3) = 4 相关知识点: ...
A straight line passing through the center of a circle is called a ___. A. radius B. diameter C. chord D. tangent 相关知识点: 试题来源: 解析 B。选项 A“radius”是半径;选项 B“diameter”是直径;选项 C“chord”是弦;选项 D“tangent”是切线。过圆心的直线是直径。反馈 收藏 ...
Which function represents the upper half of the circle? A. y = √(25 - x^2) B. y = -√(25 - x^2) C. y = 5 - x D. y = x - 5 相关知识点: 试题来源: 解析 A。解析:对于圆的方程 x^2 + y^2 = 25,上半圆的函数表达式为 y = √(25 - x^2),所以选 A。
英语翻译The center coordinates and the radius of the circle were calculated using a sliding segment of a predetermined number of pixels(100 pixels) that is skipped around the perimeter.翻译得好的有加分.
