What is the Cartesian equation of a circle whose centre is in the 1st quadrant with a radius of 7 and touches the x and y axes?
Centre of the circle is at (7, 7) and its Cartesian equation is (x-7)^2 + (y-7)^2 = 49
What is the area of a circle with a radius of 7 meters?
3850m is the area of the a circle whose radius of 7meaters
Why is 7 the radius of a circle whose diameter is 14?
By definition, the diameter of a circle is twice the radius.
What is the equation of the circle with a radius of 7 whose center is in the 1st quadrant and touches both the x and y axes?
Equation of the circle: (x-7)^2 +(y-7)^2 = 49
What is the radius of a circle whose diameter is 7 meters?
The diameter of a circle is twice the radius. When the diameter is 7 metres, the radius is 3.5 metres.
What is the equation of the circle with center 2 9 and radius 7?
depends on the equation.
What is the radius of a circle whose circumference is 43.96 inches?
The radius is 7 inches.
What is the diameter of a circle whose radius is 7 cm?
14 cm. In a circle, diameter is always twice the radius.
What is the equation of a circle whose centre is at -1 -7 and has a radius of 10 on the Cartesian plane?
The equation of a circle with centre (x0, y0) and radius r is given by: (x - x0)² + (y - y0)² = r² For the circle with centre (-1, -7) and radius 10 this gives: (x - -1) + (y - -7)² = 10² → (x + 1)² + (y + 7)² = 100 This can be expanded and rearranged to give: x² +2x + y² + 14y - 50 = 0
This circle is centered at the origin and the length of its radius is 7 What is the circle's equation?
x2 + y2 = 49
How do you find radius of a circle whose area is 154?
Radius of circle is the square root of 154/pi = 7 units rounded
What is the equation of a circle whose centre is at 3 -5 and meets the point of 6 -7 on the Cartesian plane?
Centre of circle: (3, -5) Distance from (3, -5) to (6, -7) is the square root of 13 which is the radius Equation of the circle: (x-3)^2 + (y+5)^2 = 13
