Answer:
The answer to your question is Circumference = 20π cm; Area = 100π cm
Step-by-step explanation:
Data
diameter = 20 cm
Circumference = ?
Area = ?
Process
1.- Write the formula of Circumference
Circumference = πd
-Substitution
Circumference = 20π
2.- Write the formula of area of a circle
Area of a circle = πr²
-Calculate the radius
radius = diameter/2
radius = 20/2
= 10 cm
-Substitution
Area = (10)²π
-Result
Area = 100π
M⁴n³(-mn)⁴
m⁴n³(-m⁴n⁴)
-m⁸n⁷

Answer7
Answer:
x = -7
Step-by-step explanation:
Two parallel lines are lines that never intersect each other.
The y-axis can be written as x = 0.
Then if we want a parallel line to this one, it must be something like x = b
such that b ≠ 0.
Now we want that the distance between our line and the line x = 0 is 7 units to the left
(remember that the left is the negatie side of the axis)
then we can write:
b - 0 = -7
b = -7
The parallel line is x = -7
