Answer:
38.77 yd³
Step-by-step explanation:
The volume of the sphere can be determined by using the formula 4πr³/3.
[Where "r" is the radius of the circle].
We are given that:
Radius of circle = 2.1 yd
When we substitute the radius in the formula, we get;
⇒ 4 × π × (2.1)³/3
Let π be substituted as 3.14. Then;
⇒ 4 × π × (2.1)³/3
⇒ 4 × (3.14) × (2.1)³/3
When evaulating the cube of 2.1, we get;
⇒ 4 × (3.14) × (2.1)³/3
⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3
When simplified, we get;
⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3
⇒ 4 × (3.14) × (2.1) × (2.1) × (0.7)
⇒ 4 × (3.14) × (4.41) × (0.7)
⇒ (12.56) × (4.41) × (0.7)
⇒ 38.77272 ≈ 38.77 yd³ (Rounded to nearest hundredth)
Therefore, the volume of the sphere is 38.77 yd³.

For which number is the experimental probability closest to the theoretical probability
Answers
Using it's concept, it is found that the experimental probability is closest to the theoretical probability for number 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The theoretical probability is calculated before any experiments, while the experimental probability is calculated after experiments.
Considering that the sections are equal-sized, the expected frequency for each section is given by:
Ef = 450/8 = 56.25.
The closest frequency to 56.25 is of 58, associated with number 1, which is the one that has the closest probabilities.

A bucket can hold a total of 5 gallons. If the bucket is 45% full, how much water is in the bucket?
Answers
The question is an illustration of volume, and the amount of water in the bucket at 45% full is 2.25 gallons
How to determine the amount of water?The capacity of the bucket is given as:
Bucket = 5 gallons
At 45% full, we have:
Capacity = 45% * 5 gallons
Evaluate the product
Capacity = 2.25 gallons
Hence, the amount of water in the bucket at 45% full is 2.25 gallons
