To find the length of the radius of the circumcircle of an equilateral triangle with a side length of
The length of the hypotenuse is p−a−b=32−694=594. From the formula A=rs, where A is the area of a triangle,r is its inradius, and s is the semiperimeter, we can find that r=2032/2=54. It is known that in a right triangle, r=s−h, where h is the hypotenuse, ...
If we solve this formula for r, we get r=C2π, and this provides a formula we can use to find the radius of a circle given its circumference.Answer and Explanation: We are given that the circumference of a circle is 30 centimeters, ...
If a circle has a radius of 5 cm and an arc of length 3 cm, what is the measure of the central angle in radians? A. 0.6 radians B. 0.8 radians C. 1.2 radians D. 1.5 radians 相关知识点: 试题来源: 解析 A。弧长公式 l = rθ(l 是弧长,r 是半径,θ是圆心角弧度),则θ =...
In geometry, Arc is the part of circumference of a circle. It is a smooth curve with two end points. The length of the arc that subtend an angle (θ) at the center of the circle is equal 2πr(θ/360°). Learn more about arc at BYJU’S.
The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples
