Our first step is to figure out what formulas are needed for diameter, circumference, and area of a circle.
Diameter is simply twice the size of the radius so:
2 * radius = 2 * 40 feet = 80 ft.
Circumference = 2 * pi * radius = 80 ft * pi
If we say that pi = 3.14, then:
circumference = 251.2 ft.
Area = pi * radius^2 = pi * 1600 ft^2
Once again, if we assert pi = 3.14, then:
area = 3.14 * 1600 ft^2 = 5024 ft^2.
X = 6
9/12 = 0.75
6/8 = 0.75
Answer:
X = 30°, y = 15° and z = 150°.
Reason: Look below.
Step-by-step explanation:
Hey there!
When we look into the figure, we find that;
For x:
x+ 2x + 90° = 180° {Being linear pair}
or, 3x = 180°-90°
or, 3x = 90°
or, x= 90°/3
<u>Therefore, X = 30°.</u>
For y :
2y = x = 30° {Alternate angles are equal}
or, 2y = 30°
y = 30°/2
<u>Therefore, y = </u><u>1</u><u>5</u><u>°</u>
For z:
2y + z = 180° { Being linear pair}
or, 30°+z = 180°
or, z = 180°-30°
or, z = 150°
<u>Therefore, z = 150°.</u>
