If the ratio of the width to the length is 1 : 2 then, we can represent their respective lengths using x and 2x.
Width = x
Length = 2x
2(x) + 2(2x) = 324
2x + 4x = 324
6x = 324
x = 54
2x = 108
The width is 54 ft. and the length is 108 feet. Hope this helps!
Answer:
Total area is 198.6cm²
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes.
Step one
From the given figure the two semi circles left and right can be resolved as a whole (a complete circle) with diameter d 10cm
Radius r = 10/2= 5cm
Area of circle A= πr²
A= 3.142*5²
A= 3.142*25
A= 78.55
A= 78.6cm²
Step two
The remaining part of the shape is a rectangle with length (22-10)= 12cm
I.e the 10 is as a result of the radius of the two semi circles = r+r= 5+5=10
The rectangle has a width of 10cm
Area of rectangle A=12*10= 120cm²
Hence the total surface area of the shape
Total area = 120+78.6
Total area = 198.6cm²
I believe all you do is multiply
Answer:
27
Step-by-step explanation:
(30)-4+2-1
30-4= 26
26+2=28
28-1=27
Based on definition of <em>unit</em> circle and <em>angle</em> properties on <em>Cartesian</em> plane, we find the following results: A: π/5, B: 3π/7, C: 4π/3.
<h3>How to determine angles in a unit circle</h3>
<em>Units</em> circles are commonly used to understand angles and <em>trigonometric</em> functions in a simple way. Vectors in a <em>unit</em> circle are <em>ordered</em> pairs of <em>polar</em> form: (x, y) = (cos θ, sin θ).
To solve this problem, we must take these tips into account:
- Angles in the <em>first</em> quadrant are within 0 < θ < π/2.
- Angles in the <em>second</em> quadrant are within π/2 < θ < π.
- Angles in the <em>third</em> quadrant are within π < θ < 3π/2.
- Angles in the <em>fourth</em> quadrant are within 3π/2 < θ < 2π.
Then, we have the following results: A: π/5, B: 3π/7, C: 4π/3.
