11.0
38.5
42.8
22.0

Answer 3

11.0: 34.6 (rounded to nearest ten)
38.5: 121.1 (rounded to nearest ten)
42.8: 134.6 (rounded to nearest ten)
22.0: 69.1 (rounded to nearest ten)

Answer 4

11.0: 34.6 (rounded to nearest ten)
38.5: 121.1 (rounded to nearest ten)
42.8: 134.6 (rounded to nearest ten)
22.0: 69.1 (rounded to nearest ten)

For 3.5cm, circumference = 2πr = 2π(3.5) ≈ 21.9 cm (rounded to nearest ten)

Answer 5

The formula for the area of a circle is A = πr^2, where r is the radius.

For 3.5cm, the area ≈ π(3.5)^2 ≈ 38.5 square cm (rounded to nearest ten).

11.0: 380.1 (rounded to nearest ten)
38.5: 4637.2 (rounded to nearest ten)
42.8: 5725.5 (rounded to nearest ten)
22.0: 1519.7 (rounded to nearest ten)
