Answer :
To calculate the radius of a circle with a circumference of 176cm, the formula r = C / (2π) is used, yielding a radius of approximately 28.0 cm.
To find the radius of a circle when the circumference is given, we use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference, π (pi) is approximately 3.14159, and r is the radius. Given that the circumference C is 176cm, we can rearrange the formula to solve for the radius: r = C / (2π). Plugging in the values, we get r = 176cm / (2 * 3.14159) which simplifies to approximately 28.0 cm.
