Answer:
see below
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is 9 and the height is 20
V = pi ( 9)^2 ( 20)
V = 1620 pi
If we approximate pi by 3.14
V =5086.80 cm^3
If we approximate pi by pi button
V =5089.3800099 cm^3
8
round each number to the nearest 10, then
640 ÷ 80 = 8 ← estimate
Answer:
7 hours
Step-by-step explanation:
567/9 = 63
441/63 = 7
It would take him 7 hours to drive 441 miles.
Hope this helps
False because the factor tree for 61 is 1 and 61
Answer:
Expression will be 10(x - 6).
Step-by-step explanation:
Let the given number is x.
Difference of this number and 6 will be represented by
(x - 6)
Then ten times the difference of this number and 6 will be represented by
10(x - 6)
Therefore, the statement " ten times the difference of a number and six " will be represented by the expression 10(x - 6)
