Find the volume of a cylinder that has a radius of 2 kilometers and a height of 1 kilometer. Volume = km³ (Use 3.14 for pi and round your answer to the nearest tenth.)

Volume ≈ 12.5

Step-by-step explanation:

V= B*h

V=πr^2

 =π(2)^2(1)

 =π(4)(1)

 =4πkm^3

 =4(3.14)km^3

 =12.56 km^3

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
