Answer:
Step-by-step explanation:
(For a circle)
Circumference formula: π*2r
Area formula: π*r^2
1:
A)
π*2(3) =>6π=>18.84 m
B)
π*(3)^2=>9π=>28.27 m^2
2.
A)
π*2(3.1)=>6.2π=>19.47 m
B)
π*(3.1)^2=>9.61π=>30.19 m^2
For this case we have the following multiplication:

We can rewrite this multiplication in the following way:

From here, we apply the distributive property.
We have then:

Therefore, Jack's strategy is:
Write the number in an expanded form and then apply the distributive property.
