Answer:
803.84
Step-by-step explanation:
the formula for the area of a circle is A = π r2 which is pi times the radius squared.n in this case if the circumference is 8 cm then the radius would be half of the circumference which is 4. then you square 4 which is equal to 256. Then take 256 and multiply it by pi. 256 × 3.14 = 803.84. i hope this helped you.
Answer:
16π cm^2
Step-by-step explanation:
circumference of a circle = 2 * radius * π = 8π cm
radius = 4 cm
area of a circle = radius * radius * π
A= 4 * 4 * π
A= 16π cm^2
