How do you find the of a circumference of circle in math?
the formula is: circumference= p*diameter
Whats the radius of a circle with circumference 30 cm?
To find the radius of a circle with a circumference of 30 cm, we can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given C = 30 cm, we can plug this value into the formula and solve for r. 30 = 2πr r = 30 / (2π) r ≈ 4.77 cm Therefore, the radius of the circle is approximately 4.77 cm.
What is circumference of a circle with 154 square inches?
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
If the diameter of the circle is 69mm then what is the circumference of this circle?
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given that the diameter of the circle is 69mm, you can substitute this value into the formula: C = π * 69mm ≈ 216.769mm. Therefore, the circumference of the circle is approximately 216.769mm.
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
