Formula:
A = pi times r^2
the radius would be 4 because you divide 8 by 2 in order to get radius.
a = pi (4^2)
a = pi (16)
a = 3.14 (16)
area = 50.24cm ^2
The area is 50.24 cm. The formula is π·r^2. The radius is 4 cm, and you square it. 16 cm. Then you multiply 16 by 3.14 (π). And you get 50.24 cm as the area.
2/3 for 1 jar | meaning that: 1 jar: 1 cup (1/3 left) | 1 jar: 1 cup (1/3 left) | 1 jar: 1 cup (1/3 left) | 3/3 are left, and that makes another one (the 4th one).
