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:
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
Substitute the given value we get;
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
that is it its not that hard
since 2 cm=1k you divide by 2
Let and be the two points.
We have to find the distance between the two points.
The distance Formula:
Here, we are given = (5,1) and = (9,-6)
Then, the distance between these two points is given by:
Thus, the distance between the given point is .
