Express the required calculation in terms of pi
and then round to the nearest tenth.
How much fencing is required to enclose a circular garden whose radius is 26
meters?
The formula for the circumference of a circle is C=2πr, where r is the radius. Therefore, the amount of fencing needed to enclose a circular garden with a radius of 26 meters is:
C = 2π(26)
C = 52π
Rounded to the nearest tenth, this is approximately:
C ≈ 163.4 meters.
To find the amount of fencing required to enclose a circular garden, you need to calculate the circumference of the garden.
The formula for the circumference of a circle is:
C = 2πr
Where C is the circumference, π is the mathematical constant pi, and r is the radius.
Given that the radius of the garden is 26 meters, we can substitute this value into the formula:
C = 2π(26)
Simplifying the expression, we have:
C = 52π
To round this value to the nearest tenth, we can use the decimal approximation for pi, which is 3.14159.
Thus, the amount of fencing required, rounded to the nearest tenth, is approximately 164.2 meters.
