Moe painted the lid of the barrel. The circumference of the lid is 32π inches. What is the area of the lid in square inches?

A ≈ 81.487 in²

Step-by-step explanation:

You know that circumference is C = 2πr, where r is the radius.

So,

C = 2πr

32 = 2(3.14)r

r ≈ 5.093 in

We also know that the formula for the area of a circle is A = πr², so:

A = πr²

A = (3.14)(5.093)²

A ≈ 81.487 in²

the two may have that, even a breakdown is probably offered

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
