Answer : He needs to use a larger sample size to improve his experiment.
Explanation : As Johannes wants to know whether soil, water, or both are needed for plant growth. He chooses to conduct experiments on a willow tree for five years. To get the improvement in his experimental methods he can choose a larger size of the sample and test its results. As larger size will allow him to gauge accurately on the smaller factors and results will be more reliable. Larger sampling will ensure the homogeneity of the test sample, which will yield better and reliable results.

B. 1.13 inches
C. 6.80 inches
D. 390.01 inches
The arc length of circle is 6.81. thus option C is correct.
The arc length formula for a circle is times the radius of a circle. When is in radian, the arc length formula in radians is arc length = r. Arc Length = (/180) r, where r is the angle in degrees and L is the length of an arc.
The following equation is used to compute the arc length:
Where r is the radius and C is the central angle, arc length = 2r (C/360).
2(6) (65/360) arc length
The length of the arc is 6.81 inches.
As a result, option C is the proper response.
