Answer:
a. 113.1 cm^3.
b. 339.29 cm^3.
c. 18 cm.
d. 508.94 cm^3.
e. 169.65 cm^3.
Step-by-step explanation:
a. (4/3) * pi * (3^3) = (4/3) * pi * 27 = 36 * pi = 113.0973355, which is about 113.1
.
b. 113.0973355 * 3 = 339.2920066, which is about 339.29 cm^3.
c. Since the radius of a tennis ball is 3 cm, the diameter is 6 cm. There are three tennis balls, and the diameters added up become the height of the cylinder. 6 + 6 + 6 = 18 cm.
d. pi * (3^2) * 18 = pi * 9 * 18 = pi * 162 = 508.9380099, which is about 508.94 cm^3.
e. 508.9380099 - 339.2920066 = 169.6460033, which is about 169.65 cm^3.

9 is D
10 is either a or b
Answer:
no mode
The median and mode are 12
Step-by-step explanation:
The mode is the number that appears most often
Since no number repeats there is no mode
The mean is the average
Add up all the numbers
(12+12+12+12+13+13+15)/7 = 89/7 = 12 5/7
The median is the middle number
There are 7 numbers
7/2 = 3.5
The 4th number is the median
The 4th number is 12
The mode is the number that appears most often which is 12
