The length of b and angle B and C are 3cm, 45 degrees and 79 degrees respectively.
<h3>How to determine the parameters</h3>
To determine the angles and length of sides, we use the sine rule
The sine rule is thus:

Given;
Let's find angle C

cross multiply
0. 682 × 3. 6 = sin C × 2. 5
sin C = 2. 4552/ 2. 5
C = 
C = 79°
To find length of b

substitute the values


b = 2. 59 cm
b = 3cm
To find angle B, we have

cross multiply
0. 682 × 2. 59= sin B × 2. 5
sin B = 0. 7065

B = 45°
Hence, the length of b and angle B and C are 3cm, 45 degrees and 79 degrees respectively.

Answer:
volume of a cylinder = 401.92cm³
Step-by-step explanation:
to calculate the volume of a cylinder , we will use the formular for finding the volume of a cylinder
volume of a cylinder = πr²h
given that
height of the cylinder = 8cm
radius of the cylinder = 4cm
volume of a cylinder = π × (4cm)² × 8cm
volume of a cylinder = π × 16cm² × 8cm
volume of a cylinder = π128cm³
value of π = 3.14
volume of a cylinder = 3.14 × 128cm³
volume of a cylinder = 401.92cm³
