An equation that represents the value of the circumference, C, of a circle with a diameter of 48 feet is C=2π×24.
The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its Centre. A meridian is any great circle passing through a point designated a pole.
Given that, a circle with a diameter of 48 feet.
Here, radius = Diameter/2
Radius = 48/2 = 24 feet
We know that, the circumference of a circle is 2πr.
Now,
C=2π×24
C=2×3.14×24
C=150.72 feet
Therefore, the circumference of a circle is 150.72 feet.

Answer:
The first number:11
The second number: 16
The third number: 64
Step-by-step explanation:
Let the first number be x
The second number be 5+x
The third number be 4(5+x)
The sum: x+5+x+4(5+x) =91
Open the brackets
x+5+x+20+4x=91
Arrange in like terms
x+x+4x+5+20=91
6x+25=91
6x=91-25
6x=66
Divde both sides by 6( the coefficient of x)
x=11
5+x=16
4(5+x) =64
