Answer:
143
Step-by-step explanation:
41 + 102 = 143
180- 143= 37
180 - 37 = 143

Answer:
42
Step-by-step explanation:
One angle of a regular pentagon = 108°
One angle of a regular hexagon = 120°.
One angle of a square = 90°
∴ ∠BAC = 360 – (108 + 20 + 90) 360 – 318 = 42°
hours did it take for oil to cover the area = 592
The correct option is B.
<h3>What is geometrical figure?</h3>
Geometrical shapes are the shapes that depict the shapes of various items. Various figures have two dimensions, while others have three. Only the x and y axes are used for two-dimensional figures, whereas the x, y, and z axes are used for three-dimensional shapes.
<h3>According to the given information:</h3>
Given,
Area = 11000m²
Radius = .10m/h
We know the area of the circle:
Area = πr²
The relation between parameter:
Area = πr²
11000 = 3.14 * (0.10t)²
Dividing both side by 3.14
11000/3.14 = (3.14 * (0.10t)²)/3.14
by solving this we get:
(.10t)² = 3503.184
.10t = 59.187
dividing both side by 0.10
t = 59.187/.10
t = 591.877
t = 592
hours did it take for oil to cover the area = 592
