Answer: 99.5
Step-by-step explanation:
398 ÷ 4
For this case we must indicate the cosine of A, of the figure shown. By definition:

Substituting the values we have:

So, we have to:

Answer:
Option D
7*9
b. 63
v=5 i=1
5+1+1= 7
x=10
10-1= 9
9*7= 63
Answer:
V ≈ 2011 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = area of base × perpendicular height
V = πr²h ( r is the radius and h the height )
Here r = 8 and h = 10, thus
V = π × 8² × 10
= π × 64 × 10 = 640π ≈ 2011 cm³ ( to nearest whole number )
