- Diameter = 51 cm
- Radius (r) = 51 cm ÷ 2 = 25.5 cm
- π = 3.14
- Circumference
- = 2πr
- = 2 × 3.14 × 25.5 cm
- = 160.14 cm
- Area of a circle
- = πr^2
- = 3.14 × (25.5)^2 cm^2
- = 3.14 × 25.5 × 25.5 cm^2
- = 2041.785 cm^2

Answer:
No
Step-by-step explanation:
1. 5 cups of cornmeal=2 cups of water. Using 115 cups of cormeal would mean you need 287.5 cups of water, not 3.
3 is too little
2: If you use 5 cups of water for every 3 cups of cornmeal, for 3 cups of cornmeal you'd need like 6.5 cups of water, not that high of a number.
Let x be the number.
Set up an equation:
2x - 2/3x = 20
Simplify:
1 1/3x = 20
Divide both sides by 1 1/3
X = 15
The number is 15
