Given:
Base area = 4π mm²
Height = 10 mm
To find:
The volume of the cylinder.
Solution:
Base of the cylinder is circle.
Area of the base = πr²
πr² = 4π
Volume of the cylinder = πr²h
Substitute 4π in place of πr².
= 4π × 10
= 40π mm³
The volume of the cylinder is 40π mm³.
Thats means angle BEC is 63. By the vertical angle theorem AED is the same. 3x-27 when x=30 is also 63.

Given:
and
.
To find:
The relationship between the ratios.
Solution:
We have, two ratios in the fraction form.
and 
First ratio = 
= 
=
(Cancel out the common factors)
First ratio = Second ratio
Since, the both ratios are equal to each other, therefore, the given ratios are equivalent ratios.
