x^3 + 64 = 0
Subtract both sides by 64:
x^3 = -64
x = -4
2a + 8b + 10
-3a + 7b + 16
2a + 8b + 10 - 5a -b +6= -3a + 7b +16
Next, group the similar figures
2a - 5a + 8b - b + 10 + 6= -3a + 7b + 16
Upper half of the data: 81 lower half of the data: 98
Use the formula of v = pi.(r^2).h that gives approximately v = 3.14x16x9 that gives approximately 452.16
