Answer:
The smallest angle of the triangle is
Step-by-step explanation:
we know that
If the sides of a triangle are ,
, and
, then
we have a right triangle
because, applying the Pythagoras theorem
-------> is true
Remember that the measure of the smallest angle of triangle is the opposite angle to the smallest side
so
Let
A-------> the measure of the smallest angle
Round to the nearest degree
The diameter of the tank = 9 feet
So radius is = feet
Height of the tank = 25 feet
The top of the tank must be circular with same radius as 4.5 feet
So, to calculate the area of the tank and top, we will add the curved or lateral surface area of tank and area of circle
Curved or lateral Surface area of cylindrical area = 2*PI*r*h
= = 706.50 square feet
And area of the circular top = PI*r²
= = 63.585 square feet
So, total area that will be painted = = 770.085 square feet
Or rounding up to 2 decimal places = 770.09 square feet.
