6 mins 38 seconds
.8 of 60 secs is 48 seconds so his time is 6 mins and 48 seconds, cutting off 10 seconds gives a new time of 6 mins 38 seconds
Answer:
1. V={π(3^2)*9 in^3}/3=84.82 in^3
2. V= {π(7^2)*11 in^3}/3=564.44 in^3
3. V= {π(15^2)*20 in^3}/3=4,712.39 yd^3
Step-by-step explanation:
V=π(r^2)h
Answer:
392
Step-by-step explanation:
$6.50 I guess, because I added $5 and $1.50 and got $6.50
Length = 20 ft
If he uses 60 ft of fencing to line his rectangular backyard, then the perimeter is 60 ft.
Perimeter formula is ((Width × 2) + (Length × 2))
10 × 2 = 20
20 × 2 = 40
40 + 20 = 60
