Answer:
A = 0.785m²
B = 31400cm²
C = 7850cm²
D = 785,000mm²
Step-by-step explanation:
To solve this question, we'll have to find the area of a circle which is
Area of a circle = πr²
1. The diameter of the circle = 1m
Area of a circle = πr²
r = radius of the circle
π = 3.14
Radius = diameter / 2
Radius = 1 / 2 = 0.5m
Area = 3.14 × (0.5)²
Area = 3.14 × 0.25
Area = 0.785m²
2. Radius = 100cm
Area of a circle = πr²
Area = 3.14 × (100)²
Area = 3.14 × 10000
Area = 31400cm²
3. Diameter = 100cm
Area = πr²
Radius = diameter / 2
Radius = 100 / 2
Radius = 50cm
Area = πr²
Area = 3.14 × (50)²
Area = 3.14 × 2500
Area = 7850cm²
4. Radius = 500mm
Area = πr²
Area = 3.14 × (500)²
Area = 3.14 × 250,000
Area = 785,000mm²
Answer:
Angle 2 = 120 degrees, Angle 1 = 60 degrees
Step-by-step explanation:
Since a straight angle is 180 degrees, you have to add up the 2 angles to 180.
x+x+60=180
2x+60=180
2x=120
x=60
Angle 1 = 60
Angle 2 = 60+60=120

Writing the domain in words: negative infinity to three halves and three halves to infinity
So, Option A is correct.
Step-by-step explanation:
We need to find domain of the function: 
<u>Domain:</u>
The domain of function is defined as all the input values for which the function is defined.
In other words we can say that any value of x that makes the denominator zero is not considered as domain of function.
In the function given:
if x= 3/2 then the denominator will be zero and the function will not be defined.
So, value of x should be x>3/2 or x<3/2
We can write domain as: (-∞,3/2)(3/2,∞)
3/2 can be written as three halves.
Writing the domain in words: negative infinity to three halves and three halves to infinity
So, Option A is correct.

Answer:
C and D
Step-by-step explanation:
D is the exact same.
For C this is already proven but you can test this by choosing any number for K (4) and multiply it by 1/2. You get 2 which is the same as 4/2.
