Sylvia has 51.78 pounds of dirt. She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket. Are there enough
antoniya [11.8K]

Answer:

There isn't enough buckets for all of the dirt to be in a bucket.

Step-by-step explanation:

From the question,

She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket.

Hence, the total number of dirt that can be in the 20 buckets is

20 × 2.56

= 51.20 pounds of dirt

Slyvia has 51.76 pounds of dirt.

51.76 - 51.20

= 0.56 pounds of dirt.

From the above calculation we can say that there isn't enough buckets for all of the dirt to be in a bucket

HELP QUICK !’ ***What is the area of a circle with a diameter of 126 in?
Vladimir79 [104]

Answer:

49,850.64

Step-by-step explanation:

To find the area of a circle, you must use the formula pi r ^2 (pi r squared).

In this case, we are using 3.14 for pi, so we can add that into the formula.

3.1r^2

We also know the radius, so we can add that in too.

3.14 x 126 ^2

Now solve.

126^2 = 15,876

15,876 x 3.14 = 49,850.64

49,850.64 is the answer.

Hope this helped!
