It takes Jill 2 hours to run 14.5 miles. At this rate, how far can she run in 3 hours?

21.75 miles in 3 hours

Step-by-step explanation:

first you will divide 14.5 miles by the 2 hours it took. you will get 7.25 miles. so jill can run 7.25 miles in 1 hour. next you want to multiple the 7.25 miles by the 3 hours and you get your answer. hope this helped!

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!
