Answer:
Step-by-step explanation:
We want to to rewrite
Use difference of two squares to get:
This implies that:
This finally simplifies to:
Therefore the required product is
Answer:
Area ≈ 50 cm²
Circumference ≈ 25 cm
Diameter ≈ 8 cm
Radius ≈ 4 cm
Step-by-step explanation:
Area:
Formula = πr²
Area = 3.14 * (4*4)
Area = 3.14 * 16 ≈ 50 cm²
Circumference:
Formula = 2πr
Circumference = 2 * 3.14 * 4
Circumference = 8 * 3.14 ≈ 25 cm
Diameter:
Diameter is the distance of the line that goes through the center of the circle and touches areas of the circumference.
It is given as 8 cm
Radius:
Formula = 1/2d
D = 8
1/2 8 = 4 cm

Answer:
Step-by-step explanation:
The equation of a line in point-slope form is
where y1 and x1 are 2 known points, and m is the slope of the line. So simply just fill in the blanks.
y is a variable so it is left alone (since there is no subscript).
y1 we are told is 1.
m we are told is -3 (the slope)
x is a variable so it is left alone (since there is no subscript).
x1 we are told is 6.
