Answer:
(A) The length of the diameter of a sphere is two times the length of the radius of the sphere
Step-by-step explanation:
Sphere: A round solid figure, or its surface, with every point on its surface equidistant from its center.
Also, The length of the diameter of a sphere is two times the length of the radius of the sphere that is where D is the diameter and r is the radius of the sphere.
Therefore, out of all the options given, only Option (A) is the correct option because it properly describes the statement about sphere.

We know that the percentage amount of any number can be found by first converting the the given percentage to a fraction and then multiplying it by the given number. Thus, in our case, the exact value, that is 48% of 1165 can be calculated as follows:
We know that
Therefore, 48% of 1165 can be re-written as:
This can be calculated as [tex]0.48\times 1165=559.2[/tex
Therefore The exact value that is 48% of 1165 is 559.2
The number of basketball that will fill up the entire office is <u>approximately 16,615.</u>
<em><u>Recall:</u></em>
Volume of a spherical shape =
Volume of a rectangular prism =
<em><u>Given:</u></em>
Diameter of basketball = 9.5 in.
Radius of the ball = 1/2 of 9.5 = 4.75 in.
Radius of the ball in ft = 0.4 ft (12 inches = 1 ft)
Dimension of the office (rectangular prism) = 20 ft by 18 ft by 12 ft
- First, find the volume of the basketball:
Volume of ball =
Volume of basketball =
- Convert to
<em>Therefore,</em>
- Volume of basketball =
- Find the volume of the office (rectangular prism):
Volume of the office =
- Number of basket ball that will fill the office = Volume of office / volume of basketball
- <em>Thus:</em>
Number of basket ball that will fill the office =
Therefore, it will take approximately <u>16,615 balls</u><u> to fill up the entire office</u>.
