What is the circumference of a circle that has a radius of 70ft?
C = pi * d
C = 3.14 * 140
C = ?
C=2*r*pi
C=2*70*3.14159
C=439.8226 ft
To find the circumference of a circle with a given radius, you can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference, π (pi) is a constant approximately equal to 3.14159, and r is the radius.
In this case, the radius is given as 70ft. So, you can substitute this value into the formula to find the circumference:
C = 2πr
C = 2 * 3.14159 * 70ft
Now, let's calculate the circumference:
C ≈ 2 * 3.14159 * 70ft
C ≈ 6.28318 * 70ft
C ≈ 439.822ft
Therefore, the circumference of a circle with a radius of 70ft is approximately 439.822ft.
