Answer:
725.71 cm
Step-by-step explanation:
Using the attached diagram :
Diameter of inner circle = 26
Radius of inner circle = 26/2 = 13
Radius of entire circle = 13 + 7 = 20
The Area of a circle = πr²
Area of inner circle = π13² = 169π
Area of entire circle = π20² = 400π
Area of shaded portion :
Area of entire circle - Area of inner circle
400π - 169π = 231π = 725.71 cm
58.3ft
Use the pythagorean theorem to find the answer.

Answer:
B. it makes your results more convincing
Step-by-step explanation:
A scientific experiment involves the replication and repetition of the experiment. Repetition or conducting the multiple trials of the experiment is very crucial for a scientific experiment.
The experiment is performed to understand and explain the natural phenomenon and the repetition of the experiment ensures that the results obtained from these trials are efficient either to support the hypothesis or to disprove the hypothesis.
Experimenting with multiple trials removes the chances of errors in the experiment, increases the efficiency and strengthens the results to prove or disprove the hypothesis. In other terms, it can be said that it makes the results more convincing.
Thus, Option-B is the correct answer.
<span>I would have to disagree, because to do it you would have to take 1/4 cup and multiply it by 8 and you should end up with 2 not 6.</span>
