Answer:

314 m²

Step-by-step explanation:

the surface area of a sphere (As) is

As = 4×pi×r²

our radius r (half of the diameter) here is 5m.

As = 4×3.14×5² = 4×3.14×25 = 100×3.14 = 314 m²

Given: F3 = 5 k + 515 g F4 = 945k - 713 g ; find F20

Alisiya [41]

Answer:

F20 = 15985k -20361g

Step-by-step explanation:

If we assume F3 and F4 are the third and fourth terms of an arithmetic sequence, the common difference is ...

d = F4 -F3 = (945k -713g) -(5k +515g)

d = 940k -1228g

Then the 20th term is ...

F20 = F3 +(20 -3)d = (5k +515g) +17(940k -1228g)

F20 = 15985k -20361g
