Answer: It will be 50
Step-by-step explanation:
<h3>The area of base is 0.25 square meter</h3>
<em><u>Solution:</u></em>
Given that,
The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m
To find: area of base
<em><u>The volume of cylinder is given as:</u></em>

The area of base of cylinder is area of circle

Therefore,

From given,
h = 10 m
v = 2.5 kl
1 kilo liter = 1 cubic meter
Therefore,
2.5 kl = 2.5 cubic meter
Substitute height = 10 and volume = 2.5

Thus area of base is 0.25 square meter
Answer:

Step-by-step explanation:
Read the coordinates of the points:
A(-1, 0) → A'(-1, 0)
B(0, 2) → B'(0, -2)
C(3, 2) → C'(3, -2)
D(4, 0) → D'(4, 0)
(x, y) → (x, -y)
Check:
A → A': (-1, 0) → (-1, -0) = (-1, 0) CORRECT
B → B': (0, 2) → (0, -2) CORRECT
C → C': (3, 2) → (3, -2) CORRECT
D → D': (4, 0) → (4, -0) = (4, 0) CORRECT
(6 + 3) + 21 = 6 + (3 + 21)
It's an ASSOCIATIVE PROPERTY
(a + b) + c = a + (b + c)
