Answer:
As per the given statement: A forest ranger wants to determine the radius of the trunk of a tree. She measures the circumference to be 8.6 feet.
Shape of the trunk of a tree is circle.
Use the circumference formula:
[tex]C = 2\pi r[/tex]
where C is the circumference of a circle and r is the radius of a circle.
Solve for r;
Given: C = 8.6 feet and use [tex]\pi = 3.14[/tex]
Substitute the given value we get;
[tex]8.6 = 2 \times 3.14 \times r[/tex]
Simplify:
[tex]8.6 = 6.28r[/tex]
Divide both sides by 6.28 we get;
r = 1.6942675 feet
Therefore, the trunk's radius to the nearest tenth foot is, 1.4 ft
