Answer:
452.39
Step-by-step explanation:
to find the surface area of a sphere all you need is the radius (half the diameter) and assuming the sphere touches both top and bottom that makes the radius 6 so your equation is
SA=4πr^2
SA=4*π*6^2
SA=4*π*36
SA=4*113.09
SA=452.389
then rounded up to 452.39, that is your answer
.
16.27
if 1000m rep 1km
therefore :
58.6km/h in ms = 58.6km×1000/3600
=16.277 ms
