the have identical length so to know the length of each pipe you should divide 22.4 by 7
22.4 / 7 = 3.2

Answer:
the area of a circle is πr²
the outer circle area = π 4x²
the inside circle area = π.6²=36π
the outer circle area - the inside circle area = he shaded region
π 4x² - 36π =220π cm2 it implies x²-9 =55 and x²=64, and x =sqrt(64)=8
the value of x is 8
Answer :
(1) The radius of a circle is 1.5 m.
(2) The diameter of a circle is 28 ft.
(3) The radius of a circle is 10 in.
(4) The circumference of circle is 47.14 m.
(5) The circumference of circle is 44 yd.
Step-by-step explanation :
Part 1:
Given: d = 3 m
Now we have to determine the radius of circle.
As we know that:
Radius of a circle =
So,
Radius of a circle =
The radius of a circle is 1.5 m.
Part 2:
Given: r = 14 ft
Now we have to determine the diameter of circle.
As we know that:
Radius of a circle =
So,
Diameter of a circle =
Diameter of a circle =
The diameter of a circle is 28 ft.
Part 3:
Given: d = 20 in
Now we have to determine the radius of circle.
As we know that:
Radius of a circle =
So,
Radius of a circle =
The radius of a circle is 10 in.
Part 4:
Given: d = 15 m
Now we have to determine the circumference of circle.
Formula used:
where,
C = circumference
d = diameter
So,
The circumference of circle is 47.14 m.
Part 5:
Given: r = 7 yd
Now we have to determine the circumference of circle.
Formula used:
or we can write,
where,
C = circumference
d = diameter
r = radius
So,
The circumference of circle is 44 yd.
