What is the formula for a circle centre C -5 2 and radius 5?
A circle with centre (X, Y) and radius R has an equation of the form: (x - X)² + (y - Y)² = R² → circle centre (-5, 2), radius 5 has equation: (x - -5)² + (y - 2)² = 5² → (x + 5)² + (y - 2)² = 5² This can be expanded and simplified: → x² + 10x + 25 + y² -4y + 4 = 25 → x² + 10x + y² - 4y + 4 = 0
What is the center and radius of the circle with equation (x 9)2 (y 5)2 64?
If you mean: (x+9)^2 + (y+5)^2 = 64 Then the center of the circle is at (-9,-5) and the radius is 8
What is the circumference of 10 cm circle?

What is the circumference of a circle if the radius is 5 cm?
The circumference of a circle if the radius is 5 cm is: 31.42 cm (radius x 2 x Pi = circumference).
The radius of a circle is 5 inches Find the circumference of the circle?
Circumference = 2 x pi x radius = 31.4159
What is the circumference of a circle if the radius is 48?
Just use 2 x (pi) x radius (pi) values is 22/7 or 3.142
What is the formula for a circle centre C -5 2 and radius 5?
A circle with centre (X, Y) and radius R has an equation of the form: (x - X)² + (y - Y)² = R² → circle centre (-5, 2), radius 5 has equation: (x - -5)² + (y - 2)² = 5² → (x + 5)² + (y - 2)² = 5² This can be expanded and simplified: → x² + 10x + 25 + y² -4y + 4 = 25 → x² + 10x + y² - 4y + 4 = 0
What is the diameter of a circle with a radius of 2.5 inches?

How many square inches in a 5 circle?
For a circle, the area is pi x radius squared. If 5 is the diameter, divide it by 2 first to get the radius. Pi is about 3.14.
How do you find circumference of a circle if you have radius?
For a circle, circumference = 2 x pi x radius.
What is the relationship between raidus and area?
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
What is the circumference of a circle with a radius of 5 inches?
Q : What is the circumference of a circle with a radius of 5 inches ? Ans: The formula to calculate the circumference is 2 X Pie X radius. The value of radius is given as 5 inches. Substituting the value of r in the above formula then we get as the value of Pie is 22/7 = 2 X (22/7) X 5 = 220/7 = 31.41 sq. Inches. Also, Q: What is the circumference of a circle with a radius of 12inches?? A: The circumference is 75.366 inches, because the formula is 2 x Pie x r
What is the circumference of a circle with a radius of 5 feet?
The circumference is pi times the diameter of the circle. Diameter is twice the radius, so the diameter is 10 feet. With pi approximately 3.14, the circumference (linear feet perimeter) is 31.4 feet.
