Answer:
3.14mm
Step-by-step explanation:
C = 2 pi r
Y has to belong to the interval [-9,-2]
-9≤y≤-2
18
324 = s^2 -->
sqrt324 = s -->
sqrt(2^2 * 9^2) = s -->
2*9 = s -->
18 = s
If you're trying to solve for r. r=35
Step 1: Simplify both sides of the equation.
r+2r=105
(r+2r)=105(Combine Like Terms)
3r=105
Step 2: Divide both sides by 3.
3r/3 = 105/3
r=35
Answer:90
