Find the radius of a circle which has a sector of area 21 square inches determined by a central angle one half radian radian. (type an integer or decimal rounded to three decimal places as needed.) R- _____ inches
t varies directly as the square root of l
t varies directly as the square root of l. If l=81, then t=10 what is the constant proportion?1. a is directly proportional to b. If a = 15, then b = 92. M varies directly as n. If n = 2/3, then m = 1/43. T varies as the square root of L. If L = 81, then T = 104. Z is proportional to the cube of d. If d = 2 then z = 55. f varies directly...

A circle is inside a square. The radius of the circle is decreasing at a rate of 1 meter per day and the sides of the square are decreasing at a rate of 5 meters per day. When the radius is 5 meters, and the sides are 18 meters, then how fast is the AREA outside the circle but inside the square changing?

Create a class named Circle with fields named radius, diameter, and area. Include a constructor that sets the radius to 1 and calculates the other two values. Also include methods named setRadius() and getRadius(). The setRadius() method not only sets the radius, but it also calculates the other two values. (The diameter of a circle is twice the radius, and the area of a circle is pi multiplied by the square of the radius. Use the Math class PI constant...

Write a shell script that given a radius, calculates the area of a circle. (Hint – don’t write this from scratch. Find another script that reads user input and performs a calculation, then modify it to meet your needs.) Save the script in your home directory with the name circle.sh The formula for calculating the area is: Area=Π*Radius2 You can use 3.14 for Π, and either do Radius*Radius or Radius^2 to get the square of the radius. Use the scale...
