Find a common denominator
the common denominator of 7 and 3 is 21
2/21 - 3/21
change the numerator
14/21 - 9/21 =5/21
Answer:
Area of the circle =
π m² or 132.25 π m²
Step-by-step explanation:
To find the area, we will follow the steps below.
First write down the formular for the circumference of a circle, then use the formula to find the radius of the circle after which you can now find the area of the circle.
That is;
C = 2πr
where c is the circumference of the circle and r is the radius of the circle
From the question given, circumference C = 23π
23π = 2π r
Divide both-side of the equation by 2π
23π/2π = 2πr/2π
23/2 = r
radius =
m
Formula for calculating the area of a circle is given by;
A = πr²
where A= area of the circle and r is the radius of the circle
A = π (
)²
A =
π m² or 132.25 π m²
Area of the circle =
π m² or 132.25 π m²

Answer:
x = 8/9
Step-by-step explanation:
6(3x - 4) = -8
Distribute the 6
18x -24 = -8
Add 24 to each side
18x -24+24 = -8+24
18x = 16
Divide each side by 18
18x/18 =16/18
Simplify the fraction by dividing top and bottom by 2
x = 8/9
Perimeter = length * 2 + width * 2. x = width. 2x = length. perimeter = 2(x) + 2(2x). perimeter = 2x + 4x. 60 (perimeter) = 6x. divide both sides by six. x = 10. width = 10. length is 2(width), so length is 20.
