If it takes a flock of birds 3 weeks to migrate 1890 miles south for the winter , approximately how many miles per day would they travel?

I think it's 270

Step-by-step explanation:

hope you do good

90

Step-by-step explanation:

there are 7 days in a week, divide 1890 and 7 to get 270. Now divide 270 and 3 to get 90

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
