Answer V≈351.86
Step-by-step explanation: V=πr2h=π·42·7≈351.85838
The formula for the volume of a cylinder is V=Bh or V=πr2h .
The radius of the cylinder is 4 cm and the height is 7 cm.
Substitute 4 for r and 7 for h in the formula V=πr2h .
V= pie (4)² (7)
v= pie ( 14) (49)
Answer:
F
Step-by-step explanation:
decimals are percentages and then fraction can be reduced into percentages so I did the math on all of them and f is the highest score
Answer:
-15/24 or -0.625
Step-by-step explanation:
-3/8 ÷ 5/9
First, we can use the multiplication fraction conversion trick to switch the last fraction's numerator and denominator
It would look like this: -3/8 x 9/5
Use the cross out method to simplify the fractions as lowest as possible
-1/8 x 3/5 = -15/24
Each train carried 64141 kg of flour and each truck carried 9163 kg of flour.
Step-by-step explanation:
Let the no. of kg of flour carried by each train be 'a'
Let the no. of kg of flour carried by each truck be 'b'
Total flour = 403172 kg
No. Of trains = 5
No. of trucks = 9
a = 7(b)
5a + 9b = 403172
5(7b) + 9b = 403172
35b + 9b = 403172
44b = 403172
b = 403172/44
b = 9163
Each truck carried 9163 kg of flour.
a = 7b
a = 7(9163)
a = 64141
Each train carried 64141 kg of flour.
