How much fencing is required to enclose a circular garden whose radius is 70 m? (round to the nearest meter)

3 answers

To find the circumference of a circle, we use the formula: C = 2πr, where C is the circumference and r is the radius.

Given that the radius of the circular garden is 70 m, we can substitute that value into the formula:

C = 2π(70) = 140π

We can now approximate the value of π to, say, 3.14:

C ≈ 140 * 3.14 = 439.6

Rounding this value to the nearest meter, the amount of fencing required to enclose the circular garden is approximately 440 meters.
Evaluate the function at the given value of the variable.
