Ok -13*-8 is 104.
-8*18q is 144q.
Combine an you get:
144q+104
Answer: 2.45346638e+19
Step-by-step explanation:
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.
Since they are vertical angles, they are equal.
5x - 53 = 3x - 7
2x = 46
x = 23
A
Answer:
1.45%+4.2%= 5.65%
100%->650
5.65%-> 36.725
650- 36.725 - 10 = 603.275
~ 603. 27
hence answer is b
