Find how fast she runs 1 km:
18/2 = 9 minutes.
So we know have K = 9t
Subtract 18 from both sides:
K-18 = 9t -18
Rewrite the right side:
K-18 = 9(t-2)
Answer:
Im not entirely sure this is right but
0 = tan^-1(20 ÷ 25)
0 ≈ 38.65°
hope i helped lol
V=4/3 x pi r cubed thats the ewuation for the volume of a sphere
If the radius is 25, the diameter is 50.
Use C = (3.14)(50)
C = 157
No need round off to the nearest tenth.
