What is the radius of a tree trunk with a circumference of 43.96 inches?
What is the relationship between the circumference and the radius of a circle? How can we calculate the radius of a tree trunk if the circumference is given?
The circumference of a circle is the distance around the circle, while the radius is the distance from the center to any point on the circle. The relationship between the circumference and the radius of a circle can be expressed by the formula: Circumference = 2 x π x radius. To calculate the radius of a tree trunk with a given circumference, we can rearrange the formula as: Radius = Circumference / (2 x π). Plugging in the values from the data given: Circumference = 43.96 inches, Radius = 43.96 / (2 x 3.14159) ≈ 7 inches. Therefore, the radius of a tree trunk with a circumference of 43.96 inches is approximately 7 inches.
