# 6 The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m. What is the area of its base?
Lina20 [59]
<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>

V = \pi r^2h

The area of base of cylinder is area of circle

Area\ of\ circle = \pi r^2

Therefore,

V = base\ area \times height

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

2.5 = base\ area \times 10\\\\ base\ area = \frac{2.5}{10}\\\\ base\ area = 0.25

Thus area of base is 0.25 square meter

What is the inverse of the function f(x) = 2x – 10?
Dvinal [7]
ANSWER:

f(x)⁻¹ = (x+10)/2

WORKING OUT:

f(x) = 2x - 10

y = 2x - 10

*Replace all 'y' values with 'x' and vice versa*

x = 2y - 10

*Make y the subject of the equation*

2y = x+10

y = (x+10)/2
