Answer:
314 mile²
Step-by-step explanation:
area = πr² = 3.14 x 10² = 314 mile²
4y+5=-31 you subtract 5 from both sides so you get 4y=-36 then you divide by 4 from both sides so you get y=-9 and to check you put -9 in for y and multiply 4 and -9 add 5 to get -31
6 divided by 8 is 0.75. So 0.75 is your answer. :)
There are three feet in a yard, so it is 3 and 1/3 yards wide, and 4 yards long.
you can just multiply both numbers together to get your answer, 40/3 or 13 1/3 yards.
