Find the area and the circumference of a circle with diameter 8 ft.
2 answers:
ANSWER
Circumference=8πft
Area=16π ft²
EXPLANATION
The circumference of a circle calculated using the formula:
C=πd
The diameter of the circle is 8ft.
The circumference is
C=8π ft.
The area of a circle is given by:
A = πr²
Where r=8/2=4 ft is the radius of the circle.
Therefore the area is
A = π×4²
A=16π ft²
Answer:
Area: pir^2
r=4
4pi^2
if pi=3.14
then the area is 50.24ft^2
Circumference: pi x d
d=8
8pi
if pi=3.14
then the circumference is 25.12ft.
