Step-by-step explanation:
Answer:
a² + b² = 68
a3 + b3 = 520
Step-by-step explanation:
Given :
a + b = 10 (1)
ab = 16 (2)
A. Find a² + b²
(a + b)² = a² + 2ab + b² (3)
Substitutite the values of (1) and (2) into (3)
(10)² = a² + 2(16) + b²
100 = a² + 32 + b²
Subtract 32 from both sides
100 - 32 = a² + b²
a² + b² = 68
B. a^3 + b^3
(a + b)^3 = a^3 + b^3 + 3ab(a + b)
(10)^3 = a^3 + b^3 + 3*16(10)
1000 = a^3 + b^3 + 480
a^3 + b^3 = 1000 - 480
a3 + b3 = 520

The approximate volume of each slice will be 63.5 inch². The total cake is divided into the four cylindrical slice.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
The volume of the slice is;
![\rm V = \pi r^2 h\\\\\ \rm 81 \pi = \pi \times (r)^2 \times 4 \\\\ r= 4.5 \ inch](https://tex.z-dn.net/?f=%5Crm%20V%20%3D%20%5Cpi%20r%5E2%20h%5C%5C%5C%5C%5C%20%5Crm%2081%20%5Cpi%20%3D%20%5Cpi%20%20%5Ctimes%20%28r%29%5E2%20%5Ctimes%204%20%5C%5C%5C%5C%20r%3D%204.5%20%5C%20inch)
If the grandma cut four pieces, is the approximate volume of each slice that Hattie's grandma cut will be;
The approximate volume of each slice will be;
![\rm V = \PI r^2 h \\\\ \rm V = 3.14 \times (4.5)^2 \times 1 \\\\ V=63.5 \ inch^2](https://tex.z-dn.net/?f=%5Crm%20V%20%3D%20%5CPI%20r%5E2%20h%20%5C%5C%5C%5C%20%5Crm%20V%20%3D%203.14%20%5Ctimes%20%284.5%29%5E2%20%5Ctimes%201%20%5C%5C%5C%5C%20V%3D63.5%20%5C%20inch%5E2)
Hence, the approximate volume of each slice will be 63.5 inch².
