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.
Answer:
-9/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-12)/(0-(-2))
m=-9/(0+2)
m=-9/2
Answer: B, C, A, A, D
Step-by-step explanation:
2.04 divided by 4 is £0.51 per roll
