Answer:
Step-by-step explanation:
cost is 20 fee + .25 per mile.
c =20+0.25m
$8.50 minus $14.00 would be -5.5 so the answer is -5.5$
To solve this problem and calculate the area of the sphere, you must apply the following formulas:
Formula N° 1:
V=4/3(πr³)
V is the volume of the sphere (V=3,000π m³).
r is the radius.
Formula N° 2:
A=4πr²
A is the area of the sphere.
r is the radius.
As you can see, you don't have the value of the radius "r". So, you must rewrite the Formula N° 1, and clear "r":
V=4/3(πr³)
(3,000)(3)=4πr²
r³=9,000/4π
r=(9,000/4π)<span>^1/3
</span> r=13.1037 m
Then, to calculate the area of the sphere, you must substitute the value of "r" into the Formula N° 2:
A=4πr²
A=4π(13.1037)²
A=2,158 m²

The answer is: 2,158 m²
12 x 8% = .96 (tax)
So 12 + .96 = $12.96 total
Answer:
3.6
Step-by-step explanation:
I would think this because you went up by 1 on every single one of them so I would think 3.6 correct me if I am wrong.
