Please help me. Please dont answer if you dont know. i will give brainliest. thankyou, have a great day! :)

1. 3,077.2 cm³

2. 1,808.6 ft³

3. 602.9 in.³

4. 230.8 yd³

5. 191.8 m³

6. 70.3 in.³

Step-by-step explanation:

Recall: Volume of cylinder = πr²h

1. r = 7 cm

h = 20 cm

π = 3.14

Volume = 3.14*7²*20 = 3,077.2 cm³

2. r = 8 ft

h = 9 ft

π = 3.14

Volume = 3.14*8²*9 ≈ 1,808.6 ft³

3. r = ½(8) = 4 in.

h = 12 in.

π = 3.14

Volume = 3.14*4²*12 ≈ 602.9 in.³

4. r = 3½ yd = 3.5 yd

h = 6 yd

π = 3.14

Volume = 3.14*3.5²*6 ≈ 230.8 yd³

5. r = ½(5.3) = 2.65 m

h = 8.7 m

π = 3.14

Volume = 3.14*2.65²*8.7 ≈ 191.8 m³

6. r = 1.9 in.

h = 6.2 in.

π = 3.14

Volume = 3.14*1.9²*6.2 ≈ 70.3 in.³

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
