Answer:
180.6 cubic inches. (Nearest tenth is the same as 1 decimal place)
Step-by-step explanation:
The volume of a cylinder formula is:
V
=
π
r
2
h
The diameter is
10
inches, well half of the diameter is
5
inches which is the radius. Radius is half of the diameter.
If you want the diameter back, just double it.
5
+
5
=
10
.
So we can now plug the numbers into the formula.
V
=
π
(
5
2
)
(
2.3
)
V
=
π
(
25
)
(
2.3
)
(5 Squared =25)
V
=
57.5
π
But if you didn't want it in terms of
π
, so you multiply:
57.5
×
3.14
=180.55
but rounding that to the nearest tenth is the same as rounding to
1 decimal place so you get
180.6 cubic inches.
Answer:
405.80
Step-by-step explanation:
So, we know Carlos ran 21 miles per week, for 12 weeks....
That makes 21 mi/wk x 12 weeks = 252 miles.
Then we know each km is 0.621 mile.
So, we divide 252 miles by 0.621 mile/km to get= 405.80 km
Dividing miles by miles/km gives us the unit we want (km).
<u>There was a trap in this question,</u> because if instead of dividing the 252 miles by 0.621 you would have multiplied it, you would have gotten another answer listed... just not the right one. :-)
Answer:
5 rooms
Step-by-step explanation:
4 rooms = 9 hours
9 hours = 540 minutes
1 room = 540 ÷ 4 = 135 minutes
60 x 12 = 720 minutes (12 hours)
720 ÷ 135 = 5.33333
5.3333 estimated to nearest whole number = 5
Answer:
2 3/4
Step-by-step explanation:
Her 3rd longest piece is 5 1/2 so half of 5 and 1/2 is 2 3/4
To write this as an improper fraction you would multiply 9 by 1 then add your product to the numerator.
9x1=9
9+8=17
17/9
Hoped this helped!
