Answer:
B. 100π
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
The radius is 5
SA = 4 * pi * r^2
SA = 4 * pi * 25
SA = 100 pi
It would take (100 km/hr)= 0.01 hr or 36 seconds.
Answer: 223.5
Step-by-step explanation:
We cannot see the triangle
she went down the slope 10.2 meters, -10.2
then she jumped down to the lake 1.5 meters, -1.5
-10.2 - 1.5 = -11.7 meters.
so she pretty much went 11.7 meters down from her original location.
