The lenght would be 12*4 is 48
Assuming that the meteor crater forms a hemisphere, the formula for the surface area of the crater would be 2(pi)(radius^2). Set the crater equal to the formula for a hemisphere and substitute pi for 22/7 and you’d get 9687 = 2(22/7)(radius^2). Do some quick magic on the calculator to simplify and you end up with about 60,889.71 = radius^2. Take the square root from both sides and you get 246.8 when rounded. That should be the length of the radius, and so to find the diameter, just multiply that by 2 to get 493.5. Now I don’t really know what shape you mean by meteor crater, so we’re just assuming here that you mean half of a sphere, or a hemisphere. Don’t know if this is what you’re looking for, so good luck.

Answer:
-5 is the slope
Step-by-step explanation:
if there's a number in front of x, it's most likely the slope.
Answer: D = 22, 67, 202, 607
Step-by-step explanation:
Given;
a₁ = 2
aₙ = 3aₙ₋₁ + 1
a₂ = 3a₂₋₁ + 1
= 3a₁ + 1
= 3(2) + 1 (recall a₁ = 2)
= 6+1
=7
a₂ =7
a₃ = 3a₃₋₁ + 1
=3a₂ + 1
= 3(7) + 1 (recall a₂=7)
=21 + 1
=22
a₃ = 22
a₄= 3a₄₋₁
=3a₃ + 1
= 3(22) + 1
= 66 + 1
= 67
a₄=67
a₅ = 3a₅₋₁
=3a₄ + 1
= 3(67) + 1
= 201 + 1
=202
a₅=202
a₆ =3a₆₋₁ + 1
= 3a₅ + 1
=3(202) + 1
= 606 + 1
=607
a₆ =607
