Chris used 45 feet of fencing to enclose a circular garden. What is the approximate radius of the garden? Use 3.14 for radius, and round answer to the nearest hundredth.
The answer is 7.17
the radius is not in fact 3.14 its actually 7.17. But the question wants you to use 3.14 for pi
yes
As the problem states, the radius is 3.14 feet.
Do you suppose that possibly you should use 3.14 for pi?
To find the approximate radius of the circular garden, we can use the formula for the circumference of a circle. The formula for the circumference is given by:
C = 2πr,
where C is the circumference and r is the radius of the circle.
In this case, Chris used 45 feet of fencing to enclose the circular garden, which means the circumference of the garden is 45 feet. Substituting this value into the formula, we have:
45 = 2πr.
Now we can solve for r by isolating it on one side of the equation. To do this, we can divide both sides of the equation by 2π:
45 / (2π) = r.
Using a calculator, we can calculate the approximate value of r by dividing 45 by the product of 2 and the value of π, which is approximately 3.14.
45 / (2 × 3.14) ≈ 7.17.
Therefore, the approximate radius of the circular garden is 7.17 feet when rounded to the nearest hundredth.
