Answer:
Step-by-step explanation:
Diameter:
A line passing through the center of the circle touching the circle at two points, is called diameter.
OR
The chord passing through the center is diameter.
It is double of the radius.
so,
Diameter = (2) (Radius of the circle)
Radius:
Diameter divided by 2.
OR half of the diameter is called radius.
So,
Radius = (1/2) (diameter of the circle)
Area of a circle:
Area of a circle =πr^2
Using π=3.14
Area ≈ (3.14) (radius squared)
Circumference of a cricle:
It is equal to 2πr
If π=3.14, then 2π=6.28
Circumference ≈ (6.28) (radius of the circle)

Answer:
To convert a degree measure into radians, you multiply it by π/180, π = 3.14 btw, so 25 * π/180 = 25*3.14/180 = 78.5/180 = 0.43633., which is 0.44 to the nearest hundredth.
Step-by-step explanation:
We can make this expression to find out what 49% of 3120 and 2130:
49% * 3120
49/100 * 3120
152880/100
1528.8
49% of 2130
49/100 * 2130
104370/100
1043.7
F(x) = (x - 4) (x^2 + 4) would be your answer.
