What is the circumference of a circle with an areaf 169 pi square centimeters?
pi*radius2 = 169*pi Divide both sides by pi then square root both sides to find the radius: radius = 13 and 2*13 = a diameter of 26 cm
What the formula in circle?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What is the formula for finding the radius of a circle when you have the perimeter?
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
What is the circumference of a circle with radius 5x?
Circumference of a circle = 2*pi*radius or diameter*pi
How do I measure different parts of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared Radius of a circle = diameter/2 Degrees around a circle = 360 degrees
What is the diameter of a circle that is 169 pi square yards?
Use the formula for the circle: area = pi x radius squared. Replace the area, and solve for the radius. Multiply the radius by 2 to get the diameter.

What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
What the formula in circle?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What do you multiply the radius by?
circumference of a circle = 2*pi*radius area of a circle = pi*radius squared
What is the formula for finding the radius of a circle when you have the perimeter?
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
What is the standard equation of the circle?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What is the radius of a circle that has a circumference of pi?
radius = pi/(2*pi) = 1/2 or 0.5
What is the circumference of a circle with a radius of 7 and 3 for pi?
Circumference of a circle = 2*pi*radius or diameter*pi
What is the circumference of a circle with radius 5x?
Circumference of a circle = 2*pi*radius or diameter*pi
How do I measure different parts of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared Radius of a circle = diameter/2 Degrees around a circle = 360 degrees
3 mathematical formulas including pi?
Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Surface area of a sphere: 4*pi*radius^2
