Answer:
this should be correct, im sorry im wrong.
Step-by-step explanation:
The equation is 40/12=3 1/3
Answer:the pages will come on the first is 210
Explanation:
Since we have given that two pages that face each other in a book
i.e. they must be consecutive to each other
so, let the first page number be x
and the second page number be x+1
According to question,

2x=421 -1
2x=420

So, the pages will come on the first is 210
So volue of a cone=area of circle base times heigt times 1/3
height=4
area of base=pi times r^2
area of abse=aprox 3.14 times 3.2^2=32.1536
32.1536 times 4 times 1/3=32.1536 times 4/3=42.87 the amount of sand is 42.9 ft^3
