Answer:
(1 ) Inner curved surface area of the well is 109.9 sq. meters.
(2) The cost of plastering the total curved surface area is 4396.
Step-by-step explanation:
The inner diameter = 3.5 m
Depth of the well = 10 m
Now, Diameter = 2 x Radius
⇒R = D/ 2 = 3.5/2 = 1.75
or, the inner radius of the well = 1.75 m
CURVED SURFACE AREA of cylinder = 2πr h
⇒The inner curved surface area = 2πr h = 2 ( 3.14) (1.75)(10)
= 109 sq. meters
Hence, the inner curved surface area of the well is 109.9 sq. meters.
Now, the cost of plastering the curved area is 40 per sq meters
So, the cost of total plastering total area = 109.9 x(Cost per meter sq.)
= 109.9 x (40)
= 4396
Hence, the cost of plastering the total curved surface area is 4396.
Explanation:
When Sean draws rays at the specified angles from the ends of the given side, they will cross (intersect) at a point that determines the length of the other two sides.
That is why the two angles and the side between them (ASA) are sufficient to specify a triangle, ensuring congruence or similarity, as the case may be.
Answer:
The maximum is 3350$
Step-by-step explanation:
As carpenter he earns 35$ per hours
As web design he earns 75$ per hours.
We know that 75>35, so for maximum earning he need to work as web designer more.
He wants to vork as a carpenter at least 10h in week and he worls 50h per week. So for a maximum he works as web designer 50-10=40 hours.
So c=10 and w=40
The equation is:
35c+75w=35*10+75*40=350+3000=3350$
