Answer:
b
Step-by-step explanation:
I can’t see the whole question, but I’m guessing that the 2,50$ is for every km of minutes or whatever.
So I would answer A 2.50x + 5 because you have to pay 5$ for sure and the rest depends on the value of x to know how much more you’re going to pay!
I hope this helped, if there’s anything just let me know! ☻
Answer:
13.) 314.2 in²
15.) 181.5 ft²
Step-by-step explanation:
The area of a circle is found using the equation:
A = πr²
In this equation, "π" represents the number pi (3.14....) and "r" represents the radius (half the diameter).
For 13.), you have been given the radius. Thus, you can substitute it into the equation and solve for "A".
A = πr²
A = π(10)²
A = π x (100)
A = 314.2 in²
For 15.), you have been given the diameter. To find the radius, you need to divide this value by 2. Once you find the radius, you can plug it into the equation and simplify like above.
diameter = 15.2 ft
radius = 7.6 ft
A = πr²
A = π(7.6)²
A = π x (57.76)
A = 181.5 ft²
Answer: 6.6ft
