To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.
Answer:
1.x=13/8-3y/8
2.x=11/3-2y/3
Step-by-step explanation:
A good way to find the answer to these questions is to find it algebraically. Let's call the first number 'n'.
n + (n + 2) + (n + 4) = 54
3n + 6 = 54
3n = 48
n = 16
Therefore the numbers are 16, 18, 20
1.6 × 1.6 × 1.6 × 1.6 = 6.5536
