Answer:

area = 147 cm²

circumference = 42 cm

Explanation:

area of a circle = \pi r²

  • \pi is 3
  • r is 7 cm

area = 3 × 7²

= 49 × 3

<u>= 147 cm²</u>

circumference of a circle = 2 \pi r

circumference = 2 × 3 × 7

<u>= 42 cm</u>

147 is the circumference.

since the directions say to use 3 as pi, and we know that the radius is 7, we can say that

3 times 7^2 = A, which is 147

How did flooding rivers contribute to the beginning of farming communities?
Shalnov [3]
Flooding rivers helped contribute to the beginning of farming communities because of sediment deposits that would be spread beyond the banks of the river to the land near rivers. This sediment helped to create highly fertile land that could then be used for farming. The mineral rich sediment helped to develop early farming and allowed for the natural cycle of rivers to boost agricultural production.
