If you are thinking diameter then you must mean circle. So
Perimeter = circumfrence(C)
The equation for the circumfrence is C = d(diameter) x pi(3.14)
All you have to do is multipld the diameter by pi(3.14)
8*3.14= 25.12 ft

Since the data given is diameter, then you have a circle as a figure to find the perimeter value. BUT the perimeter of a circle is the same at the CIRCUMFERENCE of a circle, the using the formula C = pi x diameter, then
Perimeter = 3.14 x 8 = 25.12 feet

Assuming you mean a circle, then the perimeter = Pi D = 22/7 * 8 = 25.153 feet

The formula for the perimeter of a circle is P=2pi*r. The diameter of a circle is twice the radius.
d=2r
8=2r
4=r
The radius is 4 ft.
A=2*pi*r
A=2*pi*4
A=8pi ft
You can plug 3.14 in for pi, but 8pi ft is the exact answer.
A=8*3.14
A=25.12 ft

the formula is C = pi D
which means C = 3.1416 times the diameter
this equals 3.1416 x 8 = 25.1328 feet

perimeter(circumference) = diameter x pi = 8xpi ft. you can have the perimeter by multiplying 8 by 3.1415.

Find the circumference of a circle
Circumference formula
c = d Ï
c = 8(3.141592654)
c = 25.13274123
c = 25.1 feet rounded to one decimal place.
