Mathematics
1 answer:
Reptile [31]3 years ago
6 0

Answer:

  4.5×10^17 m²

Step-by-step explanation:

The radius is half the diameter, so we can make the substitution r=d/2 into the formula to get ...

  A = 4πr² = 4π(d/2)² = πd²

Filling in the given values and doing the arithmetic gives ...

  A = 3.14×(3.8×10^8 m)² = 45.3416×10^16 m²

  A ≈ 4.5×10^17 m²

__

We round to 2 significant digits because that is the precision of the given diameter.

Pavel [41]
5x² + |x+1| > 0
5x² + x + 1 > 0
x+1 > 0 because it came from absolute
5x² > 0 because it’s squared

When you try a number you should put it in the original equality
5x² + |x+1|

Tomtit [17]

Answer:

Total tape used by marge is 6 inches .

Step-by-step explanation:
