(b)

factor=5 can only hold it

(c)

Only one arrangement is possible

(d)

we can put 5 cans into all 8 shelves

(e)

40=8\times 5

Step-by-step explanation:

We are given

an empty kitchen cabinet has 8 shelves

and each shelf can hold no more than 30 cans you want to arrange 40 cans in the kitchen cabinet

so that the same number of cans is on each shelf that you use

(a)

we can find all possible factors of 40

40=1,2,4,5,8,10,20,40

(b)

Since, an empty kitchen cabinet has 8 shelves

so, one of factor of 40 must be 8

so,

40=8\times 5

So, factor=5 can only hold it

(c)

Only one arrangement is possible

because there is only one such possible factor

40=8\times 5

(d)

Since, we got

40=8\times 5

So, we can put 5 cans into all 8 shelves

(e)

Since, there are 8 shelves

and we can put 5 cans on each shelves

so, possible arrangement is

40=8\times 5

Find the circumference of a circle whose area is 452.16 square meters ( ue 3.1416 as the value of
IrinaVladis [17]
Area of circle, πr² = 452.16

πr² = 452.16

r² = 452.16/π,            π ≈ 3.1416

r = √(452.16/π) = √(452.16/3.1416) ≈ 11.997

Circumference  = 2πr

C = 2*3.1416*11.997

C ≈ 75.38

Circumference is ≈ 75.38 m.

Hope this helps.
