Elena runs for 28 seconds and finishes at 250 seconds what is her velocity please explain
1 answer:
Answer:
The velocity is 8.93 meters/second.
Step-by-step explanation:
It is given that Elena runs for 28 seconds and finishes at 250 meters.
Here the displacement is 250 meters and the time is 28 seconds.
We know that
Substitute displacement = 250 and time = 28 in above formula.
meters/second
Hence, the velocity is 8.93 meters/second.

Answer:
Large baking dish of cylinder, cone and sphere.
Step-by-step explanation:
When we compute the volume of each of the small and large baking dish taking =3.14, we get
Volume of cylinder (small dish)= (r^2)(h)
=3.14()^2*3
=
= 21.195
Volume of cylinder (large dish)= (r)^2(h)= 3.14*(3)^2(3)
=84.78
Similarly, volume of cone (smaller dish)=
= 7.065
Volume of cone (larger dish)= 84.78
Volume of sphere(smaller dish)=
= 14.13
Volume of sphere (larger dish) = 85.17 (approx)
Hence, we get that larger baking dish have approximately same volume.
Therefore, large baking dish of cylinder, cone, sphere will be chosen.
