How much fencing is required to enclose a circular garden whose radius is 70 m? (round to the nearest meter)
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.
f(3) =
To evaluate the function f(x) at the given value of x, we substitute x = 3 into the function and solve for f(3).
f(3) = ?
To calculate the amount of fencing required to enclose a circular garden, you need to find the circumference of the circle. The formula to determine the circumference is:
Circumference = 2πr
Where "r" represents the radius of the circle (in this case, 70 m) and π is a mathematical constant approximately equal to 3.14159.
Substituting the values in the formula, we have:
Circumference = 2π(70)
Circumference ≈ 440 m
Therefore, approximately 440 meters of fencing is required to enclose the circular garden.
