The volume of the spherical piece is 288.55 cm³.
Solution:
Diameter of the sphere = 8.2 cm
Radius of the sphere = 8.2 ÷ 2 = 4.1 cm
The value of π = 3.14
Volume of the sphere 
= 288.55 cm³
The volume of the spherical piece is 288.55 cm³.
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.
From 100 to 999, all integers are three (3) digit numbers and available digits are (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
It implies that the total number of digits is 9. The next thing to do will be to arrange the 9 digits in three (3) places in such a way that repetition is allowed.
In the first place;
- the number of ways the number can be positioned since it can't be zero and seven = 8.
Hence, the first chance is 8 out of 10 chance.
In the second and third place;
∴
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is:
= 8 × 9 × 9
= 648
Therefore, the number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.
