Answer:
Step-by-step explanation:
Circumference formula: C = 2πr
Compare with given value and determine the radius:
- 2πr = 18π
- r = 18π/2π
- r = 9 m
Find the area of the cross-section.
Area formula: A = πr²
Area: A = 9²*π = 81π m²
A and D
should be the answers.
7c = 2b
If he can buy two pounds of bananas for $7 that means 2lbs is equal to $7
If it is 0.9 meters long and then he cuts the pipe into 4 equal pieces, then you would just do the equaton: 0.9÷4 and the answer would be 0.225
