Can someone help me with this circle geometry problem (question 1) ty

Radius =3cm

Diameter = 3+3=6cm

Circumference = 18.84

Area =113.04cm²

Step-by-step explanation:

Circumference = 3.14 (pi) × diameter

3.14 × 6 = 18.84 cm

Area = 3.14 × radius²

3.14 × 6²=113.04cm²

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
