five whats, inches?
An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2. Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.
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
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
A circle of radius 10cm has a circumference of 2πr cm = 2π x 10 = 62.83 cmIf the diameter equalled 10cm then the radius equalled 5 cm and the circumference of this circle = 2π x 5 = 31.42 cm
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
The circumference of a circle if the radius is 5 cm is: 31.42 cm (radius x 2 x Pi = circumference).
Circumference = 2 x pi x radius = 31.4159
Just use 2 x (pi) x radius (pi) values is 22/7 or 3.142
An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2. Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.
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
Diameter = 2 x radius = 5 inches.
Circumference = 2 × π × radius → circumference = 2 × π × 5 ≈ 31.42 units
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
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.
For a circle, circumference = 2 x pi x radius.
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
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
