Tamara needs to buy motor oil to fill 3 empty cylindrical barrels at her oral service center. each barrel is 7 ft deep and has a radius of 4 ft. what is the volume of that oil needed? use 3.14 for n.

1055.04 square feet

Step-by-step explanation:

We know that Tamara needs to buy motor oil to fill 3 empty cylindrical barrels and each barrel is 7 feet deep and has a radius of 4 ft.

We are to find the total volume of oil needed.

To find that, we will find the volume of a cylinder and multiply it by 3:

Volume of cylindrical barrel = 1055.04 square feet

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
