Answer:
~1.29 inches
Step-by-step explanation:
C = 2πr
C = 3r + 4.25
2πr = 3r + 4.25
2πr - 3r = 4.25
r(2π-3) = 4.25
r = 4.25/(2π-3) ≈ 1.29
Answer:
b = 12
Step-by-step explanation:
c^2 = a^2 + b^2
Solving for b,
b^2 = c^2 - a^2
= (13)^2 - (5)^2
= 169 - 25
= 144
or
b = 12
To set up consecutive even integers you use x for the first integer and x + 2 for the second integer. You add 2 since you are going to the next EVEN instead of just the next integer. Now we set up an equation = 798 and solve.
x + x + 2 = 798
2x + 2 = 798
subtract -2 from both sides
2x = 796
divide by 2 on both sides
x = 398
x + 2 = 398 + 2 = 400
CHECK 398 + 400 = 798
